Hackers overrode the tallest building in Cambridge, Mass., last week, turning the 21-story Green Building at MIT into a giant Tetris puzzle game controllable from a nearby joystick attached to a podium.

The successful attempt comes after a glitch-filled try to run Tetris on the same building in September of last year. Hackers used 153 wirelessly controlled color-changing LED lights for the giant game on a building that hosts MIT's Department of Earth, Atmospheric, and Planetary Science facilities.

The MIT-hosted Hack Gallery notes, "MIT hackers have long considered 'Tetris on the Green Building' to be the Holy Grail of hacks, as the side of the building is a wonderful grid for the game."

Players could control the prodigious puzzler with the ability to rotate, drop, and move blocks just like the real thing.

In a sweet twist, after beating the first level, the second level used harder-to-identify pale colors in the blocks, and the third level featured color-shifting tiles that appeared quite disorienting.
