So this guy, Colin Fahey, first wrote a 56 page research paper at MIT describing how to program some AI intelligent enough to win the computer game, Tetris.
Now he is running it on a PC that is "watching" another PC with Tetris on the monitor by using a webcam and having the AI software press the keys to play the game. (ok, in fact he just sends electrical signals through the keyboard, but pressing the keys would be a trivial matter mechanical matter)
Too much time on his hands? You tell me. As an engineer, I find it pretty cool.
