This sounds like an animation demo that was running at AppleFest SF in September, although the flyer I have doesn't refer to it by that name. The demo showed a picture of a five-sided stepped... I guess carousel is as good a name as any... that rotated with very clean shading and shadow effects while balls bounced down the steps and into tubes which ran back to the top of the steps. This isn't a very good description, I know, but if you saw it you'll remember from this. This particular demo had the images precalculated on Apple's Cray supercomputer and the animation is done by changing only the data that has to be changed from screen to screen. According to the people I asked the computer was just about 100% tied up just displaying those images. The name and address attached to the flyer is: Don Marsh MS 27-B Apple Computer, Inc. 20525 Mariani Ave. Cupertino, CA. 95014 Hope that is of some use...
