As a way to usher in Philly Tech Week, the 29-story Cira Centre in downtown Philadelphia was recently turned into the world's largest Tetris screen.
The giant game required hundreds of LED lights and two sides of the tower in order to be played. The spectacle was the brainchild of Drexel University associate professor Frank Lee, who projected a game of Pong on the side of the Cira Centre last year.
We're not sure if another skyscraper video game is planned for Philly Tech Week in 2015, but if there is, we hope they choose Galaga. [MSN]
