I am a Bryce fanatic. I used Bryce to create small animations which I don't think any other software could do it as cost effectively.
I have created some animations in the past but did not know how to post them.
Animations are with .mov extensions could be played on Quick Time. or .m4v for iPhone. or .avi
I have published a illusionary rotating on YouTube called "cube double".
Hope it will work...then I can add others with sound etc.
