PingPongPixel is an amazing art experiment. It’s an output device for a computer consisting of 8100 ping pong balls in 6 different grey tones. The machine interprets images, building them out of shaded ping pong balls at a larger than life, 2 by 3 meters size– taking up to 3 hours for each picture build. Rather then try to explain the whole process–I suggest you go watch the (amazing) video after the jump.
