A coffee pot, of course!
In 1991, computer scientists at Cambridge University were developing a camera to be used specifically for the internet. They weren’t even sure how important the internet would become, but they were sure how important it was to get a fresh cup of coffee.
The coffee pot that inspired the world's first webcam was located in the corridor just outside the Trojan Room within the old Computer Laboratory. They devised it to help people working in other parts of the building avoid pointless trips to the coffee room by providing, on the user's desktop computer, a live 128×128 pixel greyscale image of the state of the coffee pot.
This is how the state of the art image appeared
