Remote Controlled Car with Square Wheels

This remote controlled car has square wheels, and yup it actually moves, and yup the wheels actually go around.

Not being a physics major, I can't really explain it, but maybe this description from the car's inventor will help...

The weight shifting that propels the car is facilitated by a weight offset laterally from the center of the car that is moved in a rotational manner around the center of the car. The rotation is provided by a driven shaft extending vertically from the center of the car, with a lateral arm and off-set weight. As the shaft rotates, the weigh shifts in a circular manner around the car.

Got it? If that's not enough, you can always watch the video.
