Thanks Larry. They weren't supposed to make sense so much as just showing off the different animations 3D provides as options.

One thing I haven't figured out yet, is how to reduce the size of the animation for a screensaver export. I've tried changing the first object at 60% and then the subsequent objects proportionately smaller than that, even taking into consideration what the animation does to the overall size, but I can't seem to get it to shrink down so that it fits nicely in the center of my desktop.

Any suggestions would be appreciated.
