We began thinking about this piece by addressing the space we were given--a very tall window with less than 6 inches of depth. We wanted to engage people on a busy street, and immediately thought of making a giant pinball machine. Given that this was only going up for two days, we settled on having users pixelate the window. A large hopper for the spraypainted ping pong balls (donated by a Craigslister), let out a ball when the hand of the corresponding color was covered. We used the simple photo-cells to trigger the solenoids.
