Chinese Lantern is a variation on an optical illusion known as the kinetic depth effect (KDE), first reported by Musatti in 1924. In this example, the kinetic depth effect is enhanced by the tendency for light colors to pop, and for dark colors to recede.

If you can’t see the 3D effect, try imagining that you are circling above a steep crater.
