Drexel University professor Frank Lee re-created the classic Atari video game "Pong" on the 29-story Cira 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. They were controlled by a joystick about a mile away.
Drexel officials learned on Friday that 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."
