Last year, Drexel University professor Frank Lee completed his five year dream of playing a game of pong on the side of the Cira Center skyscraper, which stands at 29 stories tall.

Now, Lee has outdone himself this year to help kickstart Philly Tech Week, as he managed to project a multiplayer game of Tetris onto the same side of the Cira Center. Lee was playing the game together with none other than Henk Rogers, the managing director of The Tetris Company.

He converted an entire side of the building into a playing field, which translated roughly into 60,000 square feet of real estate, which is also made up of hundred of LED lights. The game itself is actually controlled roughly a mile away, but there seems to be no input lag.

In related news, Tetris celebrates its 30th anniversary in June of this year.
