In case you haven't noticed, we like projects that blend art with technology in cool and interesting ways. Frank Lee, a professor at Drexel University (go dragons?) and his team of hackers found a way to hack the external LED lighting system of a 29-story skyscraper in Philadelphia to turn it into a functioning game of Tetris.
It would have been cool enough if they programmed the lights to run a loop of the game like a massive light show, but Lee took his homage to the games of his youth to another level and hooked up joysticks so that people could actually battle it out in some arcade-style block dropping. We're a little jealous that we weren't there, but luckily this video exists for our/your enjoyment.
