World’s Largest Functional Tetris

La Bastille is a very-large-scale integrated art installation created by Technology House at Brown University. Containing eleven custom-built circuit boards, a twelve-story data network, a personal computer running Linux, a radio-frequency video game controller, and over 10,000 Christmas lights, La Bastille transforms Brown's fourteen-story Sciences Library into a giant video display which allows bystanders to play a game of Tetris which can be seen for several miles.
