The brainchild of Drexel University professor Frank Lee, "skyscraper Tetris" was played last night on the side of Philadelphia's 437-foot tall Cira Centre. You can watch video of it above.
Henk Rogers, the managing director of The Tetris Company, was in attendance to play the game with Lee. Tetris celebrates its 30th anniversary in June.
Last year, Lee rigged the Cira Centre for a game of Pong.
