Britt Faulstick reports on Drexel professor Frank Lee's 29-storey game of Pong:

On April 19 and April 24 Philadelphians young and old will have the chance to grab the arcade-style joystick one more time and engage in that timeless quest to spin the bouncing ball past the opponent’s paddle – writ large on the 401-foot north wall of one of the iconic buildings of Philadelphia’s skyline. More than 500 of the 1,514 LEDs affixed to Cira Centre’s shadowbox spandrels will recreate the game’s classic pixilation as competitors will go elbow-to-elbow from a vantage point across the Schuylkill River on the steps of the Philadelphia Museum of Art.
