Thanks for the link, I should have remembered to post it. A note about the .avi creation.. It gives big files. :) A simple 10 second animation was 44 megs when I did it and that was with nothing but the motion of a single object with no background. There was a light source though. Another note. If you plan to run it, shut down all other programs that might be running that you won't need. It hogs system memory rather strongly.
