The Osmos wheel, developed by a French designer, is one of the coolest automotive concepts we've seen. Not only do the Orbital Wheels, as they're known, look extremely cool, they can also change their roll angle to increase cornering stability at high speed, among other benefits. BMW and Toyota have already developed concept vehicles using the Osmos wheels, as have several motorcycle and motorscooter designers who've seen "Tron" far too many times to count. We can't wait till they're available as gold-plated 24s.
