Watch ‘World’s Largest Video Game’ played on 29-story skyscraper

More than 40 years after it was first unveiled, "Pong" is once again the biggest video game in the world. No, people aren’t turning in their Xbox and Play Station gaming systems for Atari consoles. In a project by Drexel University professor Frank J. Lee, a game of "Pong" was broadcast on the side of a 29-story skyscraper in Philadelphia.

“The idea for this project began in 2008 when I was driving East on I76 in Philadelphia at night heading towards Center City,” Lee wrote on his website. “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.”

When "Pong" was first released in 1972, it quickly became a national phenomenon. The game is essentially a rudimentary form of tennis, in which players use paddle joysticks to bounce a digital ball back and forth.

To make his dream a reality, Lee and his team installed hundreds of LED lights in the building’s façade. He said the project took nearly five years to reach completion.

If you want to see the large-scale game of "Pong" in person, Lee will be hosting a second round of the spectacle on April 24 at 8 p.m.

About 150 people will be selected to play the giant version of the game, with most recipients being chosen by a lottery selection system.
