Simple webpage animations

I stumbled across this informative site by a chap called Stu Nicholls for improving web animations and thought these two links might be useful. The demonstration is of a streaker running between two doors as you scroll your the mouse back and forth and the second link shows you how to make flicker book kind of animations with mouse control. I was surprised how simple and effective the technique is. There's a lot of other stuff there too by someone very clever but hey I'm NOT a programmer. Right back to work again...
