Snake Game on a Building

Here is yet another clever idea and excellent engineering by Polish students from Krakow. It was implemented through a microprocessor that controls all the lights in the building, which was then programmed to play this marvelous game.



P.S. The only thing that still bothers me is how did they do red and yellow light?
P.P.S. In January I've been posting about a similar idea to play Tetris.
