SnOil, one of the coolest physics/art projects!!

SnOil is a physical display based on ferrofluids designed by Martin Frey, a researcher and artist from the Berlin University of the Arts (or “Universit√§t der K√ľnste Berlin”, for those of us who speak German :). It employs ferromagnetic fluid and a matrix of electro magnets to create a display where the individual pixels are shaped by raising the ferrofluid above the electromagnets.

How cool is that! You can play snake on it by using the built in tilt sensors! Check out the video on his website and see how it works.
