Drexel University professor Frank Lee recreated the classic Atari game Pong on the 29-story Cira (SEHR'-ah) Centre last spring.
The building essentially became a 60,000-square-foot screen as hundreds of embedded LED lights replicated the familiar ball and paddles, which were controlled by a joystick about a mile away.
Drexel officials learned on Friday the project earned Lee the Guinness World Record for largest architectural video game display.
Other gaming enthusiasts got to share in the fun in April. Players also tried out giant versions of Space Invaders and Tetris.
