James Dyson's 'Wrong Garden' Optical Illusion Makes Water Flow Uphill

This fountain, created by inventor James Dyson and inspired by MC Escher, has water flowing up a series of ramps. Or so it appears to.

It's actually a pretty ingenious optical illusion. Water is pumped out of the tops of each ramp, cascading water down both the ramp and over its edge. Bubbles rising inside each ramp give the illusion of water flowing uphill, and all together it makes it look like the water is defying gravity. Pretty amazing stuff, and it took a solid year to design and build.
