I’m a big fan of people who do fun stuff with computers and so I am a big fan of this. These guys programmed 20 computers to play one note over and over. The resulting cacophony turns out to be a beep-boop version of the Tetris theme.

The project is simple, using the internal speaker of each computer in the class to play a different channel (instrument) of the tetris theme.
All computers are linked with the upd protocol, so not all the computers are synchronised, but for now it will be good!
