PHILADELPHIA (AP) — Hundreds of Tetris fans are expected to gather in Philadelphia to play the classic video game on the face of a skyscraper.
Images of supersized shapes are set to fall this evening on the 29-story Cira Centre.
The building has hundreds of LED lights embedded in its facade.
The gigantic game will help kick off an event called Philly Tech Week. It also celebrates the upcoming 30th anniversary of Tetris, which was created by a Russian computer programmer.
