Blinkenlights, the largest 18×8 pixels screen in the world

Blink a few times and pinch yourself. The world’s biggest interactive display (back in 2002), Blinkenlights, is constructed from 144 computer-controlled lamps behind the front windows of an 8 storey high building. You can author and submit your personal large-scale animation or have a real-time Pong match via your cell phone against other connected participants. Each independently controlled lamp can produce a monochrome matrix of 18 times 8 pixels.
