Billboard that comes and goes with the sun

The Mighty Optical Illusions website has come up with another amazing bit of trickery...this time a billboard that only appears when the sun is shining. The billboard consists of 12,148 aluminum pegs of different lengths. The difference in length causes each peg to cast a different size shadow, turning the whole billboard into a greyscale image. Brilliant!
