One of the things I noticed that others hasn't cought yet was the ball dosn't change shap enufe.. its filled with air. as it is now it looks a bit to static.. I'm hopeing the rotation on the ball will help.. it also might help a little if you have the flor that the ball hits just a little under the displayed floor.. maybe just for the first bounce.. that would add to the ilution just a little with out much work. after the first bounce you could just key frame the active floor up some..

that would work, right guys ??
