Many years ago when I was studying, boredom would be relieved by going out for a drink or two with your fellow students. At least that’s what normal students do. The geeks at MIT in the US structure their free time a bit differently. They play Tetris. On a large scale. A massive scale.
These guys decided to hack the MIT Earth and Planetary Sciences building and execute the Tetris game using the buildings room lights.
As awesome as this idea is its not however original. Brown University and Delft University managed to do something similar quite a number of years ago.
