'Pong' played on Philly skyscraper earns record

The classic Atari video game Pong is played on the facade of the Cira Center in Philadelphia on Friday April 19, 2013. Hundreds of built-in LED lights embedded in the north face of the Cira Centre were used to replicate the familiar paddles and ball with gamers controlling giant, table-mounted joysticks across the Schuylkill River from the building.
