Drexel University professor Frank Lee took over the side of the 29-story Cira Centre in Philadelphia last year to play a gigantic game of Pong, setting the Guinness World Record for the “Largest Architectural Video Game Display.” Last night he doubled the record with a massive game of Tetris. Controlled by joysticks conneted to the building’s LED lights via 4G wireless, this particular Tetris game was a competitive affair, with two teams playing on the north and south sides of the building. When one team cleared a row, the other team would get more blocks dropped on their play-field. Trash-talking was kept to a minimum, as the teams were a mile away from each other.
