I/O/D represents the coming together of Matthew Fuller, Colin Green, and Simon Pope. The group began their Web activism in 1994, with multimedia presentations via floppy disk. Their work became infamous for engulfing a computer, reducing it to a frustrating series of seemingly random generated dialogue boxes that would often crash the system. Soon after, I/O/D made the Web its target with The Web Stalker. A new type of browser, The Web Stalker offered a completely different interface for moving through pages on the World Wide Web. The user opens a URL, then watches as the "Stalker" blows open the structure and source code for that Web site, stripping the site of all content and design, and leaving only a two-dimensional mnemonic showing a skeletal map of how the Web is linked together. [1]

I/O/D 4: The Web Stalker was a new kind of web browser that decomposed websites into separate sets of entities. The texts of the site were treated as the primary resource, but were stripped of most of their formatting. Links from one file to another were mapped in a network diagram, which allowed users to visualize their path through the clusters, skeins, and aporias of files. This Map built dynamically as a Crawler function gradually moved through the network. We saw the logical structure of websites, established by the links in and between them, as another key resource, and we wanted the software to act in a modular manner, with users calling up functions, each with their own separate window, only when they needed them.

Satellite Lamps is a project that reveals one of the most significant contemporary technology infrastructures, the Global Positioning System (GPS).[1]

“Satellite Lamps shows that GPS is not a seamless blanket of efficient positioning technology; it is a negotiation between radio waves, earth-orbit geometry and the urban environment. GPS is a truly impressive technology, but it also has inherent seams and edges.”[1]

Satellite Lamps is a series of lamps that change brightness according to the accuracy of received GPS signals, and when we photograph them as timelapse films, we start to build a picture of how these signals behave in actual urban spaces.[1]

Reconnoitre is the artist duo of Gavin Baily and Tom Corby. Since the 1990s they have collaborated on artworks, texts and research that broadly explore intersections of environmental, technological and social processes. Recent work includes the use of information from the climate, meteorological and geological record to visually condense the aleatory and hidden aspects of environmental sites and landscape, and the employment of social media platforms to produce speculative geographies and experimental maps. At the heart of much of this work is an interest in data, employed as a medium beyond a conventional analytics approach, but which stresses its critical, experiential and affective potential.[1]

Benjamin Fry (born 1975) is an American expert in data visualization. He is a principal of Fathom, a design and software consultancy in Boston, Massachusetts. He is also a co-developer of Processing, an open-source programming language and integrated development environment (IDE) built for the electronic arts and visual design communities with the purpose of teaching the basics of computer programming in a visual context. The Processing design environment developed together with Casey Reas won a Golden Nica from the Prix Ars Electronica in 2005.[1]
