Look at this shape. It seems to be some kind of box with a hinge facing us. But what it is doesn't really matter. It appears that the top and bottom are different colors BUT…
Place your finger horizontally over the "hinge" part. See? The top and the bottom are exactly the same color now. What sort of wizardry is this? -via Boing Boing
