Do visit Jean Denis Haas's (an ILM animator) blog---> http://academyanimation.blogspot.com/
The Academy Blog is for the class that he is teaching right now.
He has got some nice info on bouncing balls! So, don't miss it if you wanna learn how to make bouncing ball animations!
He has also mentioned my name and my character ball tutorial in his post -----> http://academyanimation.blogspot.com/2007/01/bouncing-ball-help.html
Thanks a lot Jean-Denis!
