It’s not the first time a building was turned into a giant representation of the video game Tetris, as even in 2000 a Brown University group pulled off a similar stunt on the 10-story Sciences Library, but in that case they had permission of the university; not so in this case.

Hackers turned the Massachusetts Institute of Tehnology’s (MIT) Green Building into a huge, glorified – and playable – Tetris game. Also known as Building 54, the building houses MIT’s Department of Earth, Atmospheric and Planetary Science.
