Maybe it's not exactly about programming, but sure damned it caused it.
Back in the day I managed to create a warcraft 3 map which played tetris. The orc peons ran down with faster and faster speeds, since it was a multiplayer, we used to play it with friends. We played it so much during the day, that all of the dreams were about orcs running and exploding once you finished your line. It was the only dream I remember having.
