Trojan Room coffee pot

To save people working in the building the disappointment of finding the coffee machine empty after making the trip to the room, a camera was set up providing a live picture of the coffee pot to all desktop computers on the office network. After the camera was connected to the Internet a few years later, the coffee pot gained international renown as a feature of the fledgling World Wide Web, until being retired in 2001.

Development

The 128×128 px greyscale camera was connected to the laboratory's local network through a video capture card fitted on an Acorn Archimedes computer. Researcher Quentin Stafford-Fraser wrote the client software, dubbed XCoffee and employing the X Window System protocol, while his colleague Paul Jardetzky wrote the server program.

In 1993, web browsers gained the ability to display images; it soon became clear that this would be an easier way to make the picture available to users. The camera was connected to the Internet and the live picture became available via HTTP in November of the same year, by computer scientists Daniel Gordon and Martyn Johnson. It therefore became visible worldwide and grew into a popular landmark of the early web.
