Project Blinkenlights: Play Tetris on a building

I had seen a similar project some years ago mentioned on Steve Wozniak's website, but Project Blinkenlights took it a step further in Berlin and Paris in 2002. They offered 4 different games (Tetris, Pong, Breakout and Pacman) and anyone could play using a mobile phone.
