2.4 million people have popped in to see if there's any coffee in Cambridge university's Trojan Room coffee machine. A webcam has watched its every perk since 1991, giving it - according to the Guardian - "the same iconic status as Marconi's first crackling radio transmission or Gutenberg's first printed bible". I remember logging on back in 1996. I didn't know why, it was just one of the things you did back then, and there wasn't a whole lot else to see on the web. But the plug is to be pulled when the computer department moves into a new building later this year. Read the coffee pot's biography here or check out its current status here.
