Tetris on a Building

Okay, this is pretty awesome, I'll give them that. Some Finnish students basically programmed an entire building's dormitory lights to function effectively as a tetris game, which one of the students then begins to play using a cell phone outside the freaking building. Not a joke. I cannot imagine the time it took to do this, but it's the kind of Real Genius stuff I sort of find funny and cool. The one thing that is not clear from the video is whether a row clears when he fills in a complete row. It looks like the bottom three rows, towards the end, are all missing one cell, so the video never apparently shows a case. I can't imagine it wouldn't - what a crappy version of Tetris if you can't actually do the damn thing the game is meant to do!
