the whole concept of nyquist theorem. The wheel spins too fast for the camera to take enough samples to make it look like its always moving forward, creating an illusion that the spokes actually moved backwards a certain amount each time, making it look like it changes direction.

Thanks Dan! I did some reading up on that theorem. So can't the same effect happen when you blink your eye and there is that time when your focus gets adjusted? So the same is applied looking at a cars rims spinning on the highway, close your eyes for a second, open them and for a second or so it would seem that the wheels are going backwards. This assumes a similar wheel design.
