29-Story 'Pong' Video Game Played On Philadelphia Skyscraper [VIDEO]

It's been more than 40 years since one of the world's most famous video games, "Pong," was released, but age doesn't matter after what's been billed as "the world's biggest video game" took place on the side of a 29-story skyscraper in Philadelphia.

Drexel University professor, Frank J. Lee, started the 'Pong' project in 2008. Lee wrote on his website about the inception of the idea:

"The idea for this project began in 2008 when I was driving East on I-76 in Philadelphia at night heading towards Center City. Like many nights before, I saw the sparkling lights of the beautiful Cira Centre building. However, this night as I was staring at those lights, in my mind's eye I saw Tetris shapes outlined by those lights rotating and falling."

For those unfamiliar, the game "Pong" was released in 1972. It's a basic game like tennis, with rudimentary blocks in the place of the rackets tennis players use. The objective is to bounce the ball past the computer, or opponent, by deflecting the ball with the rectangular blocks.

For Professor Lee, the implementation process was grueling. Lee and his team installed hundreds of LED lights in the Cira Centre building's facade. According to Lee, the project took almost five years to complete.

For those that missed the first game, Lee will be hosting the second round of the display on April 24 at 8 p.m. About 150 participants will be selected using a draft lottery system. For now, just try and imagine playing Pong within whichever skyline you gaze out on.
