Abstract

This technical note republishes the 1986 paper "The Macroscope: An Interactive Videodisc System for Environmental and Forestry Education" by Hamilton and Lassoie, originally presented at the Forestry Microcomputer Software Symposium in Morgantown, West Virginia. The original paper described an interactive multimedia system combining videodisc imagery of forest ecosystems at the James San Jacinto Mountains Reserve with microcomputer-based text and graphics databases. The system introduced three epistemological entry points—Explorer, Naturalist, and Ecologist—representing spatial, taxonomic, and process-oriented approaches to ecological education. This republication provides a faithful transcription of the complete original paper, followed by reflections examining how its central ideas evolved over four decades into the current Macroscope paradigm, including the transformation from retrospective image archives to prospective sensor networks, and the expansion of the original three-domain framework into the four domains (EARTH, LIFE, HOME, SELF) that structure the Canemah Nature Laboratory's current research. The republication serves as both historical documentation and a case study in the persistence of conceptual frameworks across radical technological transformation.

1. Introduction

1.1 Context for Republication

In the summer of 1986, James P. Lassoie and I presented a paper at the Forestry Microcomputer Software Symposium in Morgantown, West Virginia. Jim was my doctoral advisor at Cornell; I had graduated three years earlier and was directing the James San Jacinto Mountains Reserve in Southern California, working with thousands of images of the mountain's flora, fauna, and landscapes. Together we had built an interactive system that let students explore an ecosystem through video imagery controlled by microcomputer.

We called it the macroscope, borrowing the term from Joël de Rosnay's 1979 book about systems thinking [1]. The name felt right: a tool for seeing patterns at scales too large for direct observation, the complement to the microscope's revelations of the very small.

1.2 Rationale

This paper is republished for several reasons:

1. As a companion to a memoir essay documenting my forty-five-year professional relationship with James P. Lassoie
2. Because the paper articulates ideas that remain central to current work—the three "epistemological entry points" described in 1986 evolved into the four domains (EARTH, LIFE, HOME, SELF) of what is still called the Macroscope paradigm
3. As a case study in conceptual persistence across technological transformation—the Pioneer 8210 videodisc player and the Apple IIe are museum pieces, but the underlying question (how to make an ecosystem legible to someone who cannot spend months in the field) remains urgent

1.3 Document Structure

ABSTRACT

The recent development of interactive video allows for the coupling of high resolution video imagery with microcomputer graphics and text to provide a multi-purpose tool which has immense applications to resource management and science education. Up to 54,000 still and motion images can be stored on a single videodisc, and each can be accessed by the computer in under 3 seconds. The macroscope is a project which combines video imagery of forest ecosystems within the Hall Canyon Research Natural Area (San Jacinto Mountains, California) with a text and graphics database implemented on both an Apple IIe and IBM PC-XT. Students can vicariously explore this natural area from various perspectives including aerially, panoramically from ridgelines, spatially from the ground, and conceptually using various classifications and database relationships. Access to each level of information is obtained by selecting from either a menu of numbered options, or by touching graphical icons or objects presented on the touch sensitive video monitor. Descriptive and bibliographic information about each feature is readily available with each video frame. Additional capabilities of the macroscope include digital processing of video imagery to map cover types, determine distributional gradients, and calculate standard measurements such as diameters and surface areas.

INTRODUCTION

The macroscope concept was conceived as an innovative approach towards rectifying a number of disturbing trends relating primarily to environmental education and resource management, these being:

1. a failure of public education to progressively incorporate environmental science studies into the basic curriculum

2. a reduction in "information transfer" between scientists and the instructional systems including public schools and undergraduate University curriculum

3. a significant decline in field trips to natural environments as a component of science education in public schools and undergraduate instruction

4. a paucity of authoritative, realistic, and relevant computer-based materials which offer a viable alternative to traditional textbooks in public education

5. a lack of accessible training opportunities for instructors to develop their own unique computer and/or video materials for the classroom and laboratory (rather than depending upon expensive, ready-made media).

These trends are well documented in the literature, including the recent report by the National Commission of Excellence in Education, A Nation at Risk: The Imperative for Educational Reform. The problems outlined by each report are numerous, including a sharp reduction in the National Science Foundation Science Education budget since 1959, declining importance of science and mathematics in the curriculum, present and future shortages of qualified teachers, obsolete curricula and equipment, and declining budgets which restrict or eliminate class field trips. The numerous reports and analyses have at least energized national interest in science and mathematics training and appear to have launched a new wave of educational reform.

There are no easy or rapid answers to the numerous problems in science and environmental education. One of the many areas likely to be modified, however, is curriculum development. Relevant, inexpensive, and innovative teaching aids or curriculum projects (e.g. films, videotapes, slides or computer programs) provide a small but important component of a successful and challenging curriculum. Indeed, two of the five criteria suggested by the National Science Teachers Association search for excellence in science education with respect to programs that foster 'science as inquiry' include "curricula as units of instruction that give attention to science processes" and "instruction that focuses on exploration rather than coverage".

Both criteria can be addressed, in part, by well designed curriculum projects, especially employing the use of computers, telecommunication, or video. Our research uses these technologies to develop curriculum projects for the ecological and forest sciences. The macroscope combines video imagery of forest ecosystem features stored on videodisc with text and graphics based information implemented on the Apple IIe and IBM PC-XT microcomputers. The database is the compilation of over twenty years of studies and research on the ecosystems of the San Jacinto Mountains, located in Southern California, Riverside County.

VIDEODISCS AND COMPUTERS

Instruction and training is a widely accepted application and a strong impetus for integrating computers and video equipment. Many early CAI (computer aided instruction) projects failed to reach their expected potential because they lacked audio and realistic video images. Some educators concluded that the addition of videodisc peripherals to CAI programs could improve the success rates of students. This has proven to be the case [2].

Training systems incorporating videodiscs are usually categorized in levels [3]. Level 1 systems are the simplest, consisting of a video player and a monitor. The player may just as easily be a videocassette player, if the material is to proceed linearly with user intervention. Most home videodisc players have internal microprocessors which allow frame search, auto stop, chapter stop and still image display through either the player's keypad or a computer-aided testing plug. Readily available level 1 players include Pioneer-manufactured machines sold under the Pioneer, Sony, Magnavox, and Sylvania brand names.

Level 2 systems consist of a videodisc player and a controller which can read digital signals encoded on the videodisc. The controller is designed to read command instructions related to the video program. Best utilized in limited, simple applications, level 2 systems offer branching from a single frame, answer analysis, and similar forms of interactivity.

Level 3 systems consist of a videodisc player, a microcomputer, an interface which ties the two systems together, a video monitor to display video and/or computer output, and software which is designed to aid content specialists in developing programs using computer screens in conjunction with video images. At a minimum, the computer controls the sequence of image strings from the videodisc player based on input from the user and control data stored on the videodisc, floppy disk, or other magnetic storage device.

Finally, level 4 interactive video was designed to increase the interactivity of the level 3 system by incorporating overlay graphics that combine the video images and computer text and/or graphics on a single screen, touch sensitive video monitors, and sophisticated course authoring software to design lessons for virtually any subject area.

The macroscope project incorporates level 3 and level 4 systems (Table 1) so that students and researchers can realistically explore a database of forest knowledge in a format simulating a field trip in the San Jacinto Mountains.

MACROSCOPE SYSTEMS OVERVIEW

The level 3 videodisc workstation (Figure 1) consists of an Apple IIe microcomputer, First Class Peripherals 10 megabyte hard disk, Amdek 300 composite video monitor, Pioneer 8210 videodisc player, and a Optical Data VAII interface. Authoring software used with the Apple system is called LaserWrite, also by Optical Data Corporation, and includes modifications made by Dr. Hamilton.

Our level 4 system utilizes an IBM PC-XT, Pioneer LDV-1000 videodisc player, Zenith ZVM-135 interlaced monitor with touchscreen, VAL Microkeyer (1150) graphics overlay system with a Tecmar Graphics Master graphics display board. We are writing application lessons using the Quest Authoring System from Allen Communication.

Table 1. Interactive video hardware, software and videodiscs.

We have taken two approaches to videodisc imagery for the macroscope -- using existing commercial videodiscs -- and creating our own unique discs. Commercially available videodiscs are now available for use in educational applications covering a somewhat diverse range of subject areas. The BIOSCIENCE DISC and LIFE CYCLES DISC by Videodiscovery were produced by faculty members at the University of Washington. Each disc contains literally thousands of stills and motion sequences covering the range of biological subjects from molecules to ecosystems. In theory, a single sided videodisc can store a maximum of 54,000 unique frames of video. Without exception, discs which are edited to contain single, unique frames are very costly to produce, a typical production cost for an original disc can exceed $100,000 if the disc contains more than 10,000 unique still frames. Disc duplication is, however, about $10 a copy after an initial $2,000 set-up. These rates assume that a videodisc producer plans to distribute copies of discs to recover expenses or make a profit. Although prices of commercially available discs vary, we have found a range of $50 to $400 for educational media (Table 1), excluding software.

An alternative to purchasing videodiscs is developing your own. The macroscope database consists of a series of approximately 10,000 images taken at the University of California, James San Jacinto Mountains Reserve. The James Reserve is a biological field station surrounded by the San Bernardino National Forest. The area has been used for research and study since 1950, and has recently been designated as a Federal Research Natural Area (RNA). Our videodisc documents the ecological features of this RNA in a highly organized manner allowing students to explore the natural environment from various perspectives including aerially, panoramically, spatially from the ground, and conceptually through classifications and relational attributes.

VIDEODISC PRODUCTION

A viable alternative to the "professional" videodisc development process is the "video check disc" [4]. Whereas the replicate videodisc costs $2,000 for the initial "stamper", a check disc is a blank "recordable optical disc" used to create a single copy of the videodisc so that the producer can check the accuracy of the premaster videotape. For single use applications, the check disc can be used as the final videodisc. Advantages of the check disc include cost ($300 vs. $2,010), convenience (the disc can be recorded while you wait at the studio), and the ability to record from 3/4 inch videotape format (1 inch type "C" videotape is recommended for replicate disc mastering [5]). The disadvantages of a check disc are poorer resolution of the video image, increased heat sensitivity which requires careful protection of the disc, and lack of cost reduction if produced in quantity. We have found that for most general purposes where resolution is not critical, the check disc is a superior alternative to the replicate process when development of unique videodiscs is required.

A major cost of producing a videodisc is the videotaping and editing procedures. If you do not own a 3/4 inch videotape recorder and broadcast quality camera, equipment rental can become costly, ranging from $100 to $500 per day. A carefully written script and a tight shooting schedule can reduce the rental time, so plan accordingly [6]. If you can borrow the equipment, or use an existing videotape, then experimentation may be possible. The single major cost is editing. A maximum of 30 minutes of motion video (30 frames per second) can be stored on each side of a disc. To conserve space for adequate still frames all motion clips should be very short. One technique to reduce editing costs is to record 10-20 frames of video for every still. This is equal to rapidly turning the camera on and off while shooting in the still/pause mode of the videocassette recorder (VCR). By using this approach, editing onto a second tape can be avoided (try to avoid "second generation" tape as this reduces the quality of the images on the videodisc), and sufficient frames from which to choose clear stills for lesson development are provided. Because still frames and motion clips are accessed from the videodisc by the microcomputer, it is not necessary to record the material on tape in any particular sequence. Professional videodisc producers may disagree with this point, only because frames which are found closer together on the videodisc are accessed more rapidly than distant frames. We do not feel this is an important consideration when the maximum access time to any frame is 3 seconds!

The macroscope imagery consists of the following inventory of video still frames (each still has 10-30 redundant frames):

• 25 step-frame panorama of the RNA watershed as viewed in wide angle from 3 ridgelines (each image overlaps by 50% with adjacent frames)
• 500 telephoto views from the same perspective as the wide angle frames
• 7 ecosystem "stands" consisting of 150 overlapping frames per stand recorded such that the series forms a spiral panorama from the ground level (herbaceous community) to a vertical frame directly overhead. The ecological diversity of each stand reflects the overall species and successional status of the James Reserve and Research Natural Area
• 200 closeup frames of plant species which occur within the RNA. Each of these frames can be "linked" to the community within the stand ecosystem where the species is known to occur.

Using a Sony video camera and portable tape deck, the videotape footage required three days of field work and two days of studio time. Species specific stills were obtained either directly in the field or transferred from existing photography by videotaping off of a slide screen (when transferring transparencies) or on a copy stand (when transferring prints). The twenty five minute "pre-master" tape was sent to SpectraImage, in Burbank, California, to master the check disc. Total cost of videotape and disc production was $600.

MACROSCOPE PROGRAM DEVELOPMENT

Developing programs for interactive video (level 3 and 4) is by far the most challenging and rigorous step in any computer assisted instructional system. Numerous software "tools" are available to aid the content expert in organizing a lesson or course [7, 8]. The most popular programs are course authoring programs or authoring systems. These may be in the form of a language, such as "Pilot" or "Super Pilot", menu-driven programs which walk you through the process of linking computer text screens with videodisc frames (e.g. Laserwrite), or elaborate systems of programs which help you to generate text, graphics (including animation), overlay or combined video and computer output, and incorporate other input devices such as mice, light pens and touch screens. Quest, by Allen Communication is an example of an authoring system. Course development tools share the common characteristic of relieving the course developer from the need to program in a higher level computer language such as BASIC or Pascal. Authoring systems do approach the complexity of a computer language but provide assistance through the use of help screens and tutorials. The most sophisticated authoring systems allow the developer to include programs written in any computer language to be "imbedded" within a lesson so a student can run a simulation or access a relational database or spreadsheet as a component of the course.

Although our project involves level 3 and 4 interactive video, the lessons written with the level 4 authoring system are at a preliminary stage. The following discussion will describe our use of the level 3 course authoring program, Laserwrite, in conjunction with macroscope videodisc atlas of ecosystems.

Laserwrite is an authoring program published by Optical Data Corporation designed to allow people with little or no programming experience the means to develop their own level 3 interactive video courses. Targeted for users of Apple computers and the VAII interface, the Optical Data Corporation system is the least costly way to add interactive video to any existing Apple II microcomputer. Laserwrite is an easy to use, although limited, authoring program which allows you to write text screens which can be linked to any sequence of videodisc frames. Users can branch to other screens from any page by entering one of five multiple choice options, true or false options, or next page option. The main program disk guides you through the process of setting up each computer page, linking videodisc frames, and selecting branching options. The end product is a student floppy disk which can be copied for multiple use. The program was written in Applesoft Basic, and works under the Prodos operating system (it is not copy protected). An IBM PC version is also available. We are currently modifying this program to support fixed disk operation, branching from touch screen or cursor location, and joystick control of videodisc frame selection.

Macroscope lessons written with Laserwrite have been organized into three distinct formats, EXPLORER, NATURALIST, and ECOLOGIST. Laserwrite creates a series of Prodos files which can be linked to one another via the branching options. A single file supports up to 38 pages of text in 40 column by 16 line format. The EXPLORER contains in excess of 30 files, or the equivalent of three floppy disks. NATURALIST and ECOLOGIST, in their current form, occupy about 25 files each, but are in a state of revision and updating as time permits. Collectively, the three can be considered a library of short lessons relating to forest ecosystems. The combined lessons can be used as a descriptive and visual database, or used independently as separate curriculum projects for forestry, ecology, or related natural sciences. At the James Reserve, instructors and researchers have used the combined database as a preliminary assistance in identifying field study sites or study organisms.

The following is a brief description of each of the macroscope programs (or indexes).

Explorer

This program considers the James Reserve landscape and ecosystems from various scales of observation. The first videodisc still frame presents a sweeping panorama of the Reserve from the highest point of the watershed (7,708 feet). The computer monitor describes the aspect and elevation, and a menu of 5 choices: scan to the right, scan to the left, scan up, scan down, and zoom to ecosystem. When the user selects a direction, the keystroke sends a command to the videodisc player to access a frame which is immediately adjacent to the initial frame. Spatially, the adjacent frame is offset by approximately 50% from the nearest frames. In this manner, the student can follow a video map of the viewshed from an oblique or panoramic perspective. If the student desires to take a closer look, the zoom to ecosystem command accesses imagery taken from the same view points, but in telephoto resolution where distinct canopy vegetation can be discerned. The commands on the computer monitor remain the same for orientation, with the exception of the zoom command, Zoom to community. Zoom to community brings the user to the ground level within a stand representative of the canopy ecosystems viewed from the landscape perspective. From the ground level, the user can view the community by scan right, left, up or down, and zoom into closeups of any species known to occur near that sight or within that plant community.

Naturalist

The naturalist programs follows a conceptual, rather than geographical matrix, useful in exploring the forest ecosystems of the James Reserve. The first menu lists five ecosystem types: wetlands, montane chaparral, mixed conifer and oak forests, conifer and oak woodlands, and meadows. After choosing an ecosystem, the menu lists three communities to select: canopy, shrub or herbaceous. Selection of a community provides a motion video sequence of a 360° view of this "strata", followed by a complete species list for that community type. Once a student selects a species, a short summary of systematic and ecological information is presented, along with a menu of communities where that species is known to occur within the James Reserve. From this menu a student can return to the community type and ecosystem or branch to an entirely different location.

Ecologist

The ecologist program is an attempt to develop a database of ecological relationships based upon the technique of gradient analysis. Because dominant vegetation in the San Jacinto Mountains follows environmental and disturbance (successional) gradients in a more or less predictable pattern, macroscope imagery can be "shuffled" to present the ecological sequence of occurrence along simple and complex environmental or temporal transitions. Mesic to xeric sites, low elevation to high elevation, post-fire to old growth, or shaded to sun-bathed are gradients which can be presented for a given location or ecosystem. Other ecological relationships are being described as macroscope lessons including wildlife interactions.

The three primary programs, EXPLORER, NATURALIST, and ECOLOGIST, are an initial attempt to use the powerful visual tools of interactive video, with the data and text management techniques of the microcomputer to compile research information within a format which is adaptable to various users needs. The immediate benefits of this system for science education stem from the unique simulation format which in concept is similar to the exploratory aspects of field science. Because the computer can be considered an "infinitely patient" teacher, the rate of student inquiry and learning is adjustable. Although Laserwrite lacks many of the sophisticated techniques of an authoring system, such as student grading, computer graphics, or advanced input devices, it is nonetheless a valuable first step towards bringing realism into the field of computer assisted instruction.

FUTURE PROJECTS AND CAPABILITIES

Our interest in level 4 interactive video is "linked" to the expanded capabilities of the 16 and 32 bit microcomputers, such as the PC and the Macintosh. An untouched research arena is the application of videodisc storage and retrieval in resource management. Level 4 authoring systems are sophisticated enough to design computer-based experts which can be used for training, simulation, and point of information on any topic. Images stored on videodisc can be retrieved and digitally processed to classify canopy types from aerial photographs or satellite imagery, maps at a variety of scales can be linked to allow a manager to zoom into spatial data of finer resolution and instantly switch between overlays of information. Our research has demonstrated capabilities for inexpensively building image libraries of vegetative photopoints so that relative canopy changes, leaf surface areas, and volume measurements can be digitally calculated with unique precision.

It is our intention to bring these important tools based upon interactive video, into the classroom to stimulate increased awareness and excitement of environmental sciences. So far our approach has been to expose as many secondary and University level teachers to the functions and capabilities of the macroscope in an effort to encourage their interest in supplementing their current computer systems with interactive video. This has been mildly successful. Our second approach is to use our system in different classroom settings to gauge student reaction to the systems. As new videodisc materials are made available along with curriculum-based programming, there will certainly be an important niche for the macroscope style approach within the classroom.

3. Reflections: Forty Years Later (2025)

3.1 On the Educational Crisis

We opened the 1986 paper with a list of five "disturbing trends" in environmental education: the failure to incorporate environmental science into curricula, the gap between researchers and instructors, the decline of field trips, the lack of good computer-based materials, and the absence of training for teachers to develop their own materials.

Reading this list forty years later, I am struck by how persistent these problems have proven. The specific technologies have transformed beyond recognition, but the underlying challenge—how to convey ecological complexity to students who cannot spend extended time in the field—remains largely unresolved. If anything, the problem has intensified: attention spans have shortened, screen time has exploded, and the gap between lived experience of nature and mediated experience has widened.

What has changed is the scale of possible response. In 1986, we were excited about reaching "secondary and University level teachers" through demonstration. Today, a single well-designed web application can reach millions. The iNaturalist platform, which I watched grow from concept to over 200 million observations, represents something we could barely imagine in 1986: citizen science at global scale, with AI-assisted species identification and instant community validation.

3.2 On the Three Epistemological Entry Points

The heart of our 1986 paper was the articulation of three "indexes" or ways of knowing an ecosystem:

• EXPLORER: spatial and perspectival, navigating the landscape through panoramic imagery and zoom levels
• NATURALIST: taxonomic and community-based, organized by ecosystem type and species
• ECOLOGIST: process and gradient-oriented, following environmental transitions from mesic to xeric, low elevation to high

These three entry points were our attempt to recognize that different users—a child, a biology major, a professional ecologist—would navigate the same database in fundamentally different ways. A child might want to "fly" through the landscape; a naturalist might want to identify a flower; an ecologist might want to understand why the vegetation changes along a slope.

Over the decades, this tripartite framework evolved into four domains: EARTH (geography, climate, environment), LIFE (biodiversity, taxonomy, ecology), HOME (human built habitat), and SELF (personal health, work, reading, writing, social connections). The addition of HOME and SELF reflected a recognition that ecological thinking does not stop at the boundary of "nature"—that the built environment and our own bodies are also systems amenable to the same observational and analytical approaches.

The word "strata" that appeared in the 1986 paper—we used it to describe the canopy, shrub, and herbaceous layers of a forest community—has also persisted. Today, STRATA is the name of the conversational interface for the Macroscope sensor networks, maintaining contextual awareness across data streams just as the original system maintained context across videodisc frames.

3.3 On the Technical Infrastructure

The hardware list from 1986 reads like an archaeological catalog:

• Pioneer 8210 videodisc player ($400)
• Apple IIe with First Class Peripherals 10 megabyte hard disk
• Amdek 300 composite video monitor
• Optical Data VAII interface ($150)
• LaserWrite authoring software ($75)
• Total videodisc production cost: $600

We were proud of that $600 figure—it represented a radical democratization of what had been a $100,000+ production process. The "check disc" approach we described, using a recordable optical disc rather than a replicated stamper, was genuinely innovative for its time.

Today, the smartphone in my pocket has more storage, processing power, and display resolution than our entire 1986 workstation. The 10,000 images we painstakingly compiled on a single videodisc would fit in a fraction of a modern SD card. More importantly, the images would be networked, searchable, and continuously updated rather than frozen on a physical disc.

But the deeper transformation is not in storage or processing—it is in sensing. The 1986 Macroscope was fundamentally retrospective: we compiled existing imagery and research into an interactive archive. The 2025 Macroscope is prospective: distributed sensor networks continuously monitor temperature, humidity, soil moisture, acoustic environments, and camera feeds, feeding real-time data streams into AI systems that detect patterns and anomalies.

The Center for Embedded Networked Sensing (CENS), which I co-founded in 2002 with $40 million in NSF funding, was in some sense the next iteration of what Jim and I were reaching toward in 1986. The "level 4 interactive video" we described—with its overlay graphics, touch-sensitive monitors, and sophisticated authoring systems—was a stepping stone toward what would become the "Robot Forest" at the James Reserve and the Very Large Ecological Array at Blue Oak Ranch.

3.4 On the Future We Imagined

The final section of the 1986 paper, "Future Projects and Capabilities," reads with a mixture of prescience and naïveté:

"Images stored on videodisc can be retrieved and digitally processed to classify canopy types from aerial photographs or satellite imagery, maps at a variety of scales can be linked to allow a manager to zoom into spatial data of finer resolution and instantly switch between overlays of information."

We got the trajectory right: hierarchical spatial data, overlay systems, digital classification of imagery. What we could not have imagined was the scale. The drone systems I demonstrated in my 2019 Cornell presentation can collect more data in a single flight than our entire 1986 videodisc database. The satellite imagery freely available through Google Earth exceeds anything we could have accessed through the most expensive government systems of the 1980s.

"Our research has demonstrated capabilities for inexpensively building image libraries of vegetative photopoints so that relative canopy changes, leaf surface areas, and volume measurements can be digitally calculated with unique precision."

This sentence describes, in nascent form, what would become phenocam networks, NDVI analysis, and the continuous monitoring of vegetation dynamics that is now routine in ecological research. The "unique precision" we were proud of in 1986 would be considered crude by today's standards—but the conceptual framework was sound.

3.5 On Collaboration Across Time

What strikes me most, rereading this paper, is the presence of Jim Lassoie's pedagogical sensibility throughout. Jim was never primarily a technologist—his passion was for teaching, for making complex ideas accessible, for meeting students where they were. The three "indexes" we developed were not technical specifications; they were pedagogical strategies, ways of honoring different learning styles and different relationships to knowledge.

Jim pivoted away from technology in the years after we wrote this paper, moving toward international conservation and community-based education. I went deeper into sensors and systems. But we were both, in our different ways, trying to solve the same problem: how to make the invisible visible, the complex comprehensible, the distant accessible.

The Macroscope endures because it was never really about videodiscs or microcomputers or touchscreens. It was about a way of seeing—a conviction that ecosystems could be made legible through thoughtful interface design, that technology could serve rather than obscure our connection to the natural world.

Richard Brautigan imagined a "cybernetic meadow where mammals and computers live together in mutually programming harmony" [9]. In 1986, Jim and I were trying to build a small piece of that meadow. Forty years later, the work continues.
