Animated Impossible Staircase

The ball bounces down and around, and back to its starting point. An endless impossible loop; going endless up the staircase, or endlessly down.

NOTE: This AVI file may not run on Netscape browsers. Netscape users should save the AVI file to a hard drive and then run the animation. Blame it on Bill Gates.
