The Massachusetts Institute of Technology has a long (long) history of student "hacks," harmless but clever pranks. Several tend to show up in any given year. Previous reasonably recent favorites (of mine) include turning a building into The One Ring, flying Nyan Cat through a lobby, and an upside-down lounge.
The students' newest adventure brought larger-than-life video games to campus, as the gridded shape of the side of the Green Building proved irresistable for a game of Tetris. The game was fully playable, with three levels that got progressively harder over time.
Alas, the video reminds us of the eternal truth of Tetris: even if you program it yourself, to run down the side of a building, you never can get the long piece when you really need it.
