Students at MIT took to the Cecil and Ida Green Building over the weekend to create an oversized, playable game of Tetris. Emulating the classic 80s video game with the help of a console and 153 color-changing LED lights, students were able to rotate and move colored blocks across the building. Like the original puzzle game, once someone lost, all of the colored blocks fell to the bottom of the building. MIT has a long history of hacking the building, including a sound meter, Oscar statue and the United States flag.
