Gamers in Philadelphia reportedly had a good time playing the good-old classic Tetris' on the side of the 29-story Cira Centre.
According to Cnet, it was the celebration of Philly Tech week for which Frank Lee (an associate professor of digital media at Drexel University) created the biggest game of Tetris ever.
The display was created by LED lights, which gamers could control just like the handheld game.
Lee said that his project began as a personal love letter to the games that he loved as a child.
