This Pool Can Create Waves In Any Shape You Want

This water pool can create waves in any shape you can imagine. Not just rough sketches, but perfectly clear shapes like hearts, stars with hard angular points, and even a musical note.

It uses computer-controlled actuators that move the water in perfect synchronisation. The computer software uses fluid dynamics algorithms to calculate the necessary motions. The whole thing looks like a computer rendering, but it's real. [YouTube via DRB]
