Hi,
last I have seen here
http://www.3dsom.com/proexamples/index.html
an interactice autorotate - the user can stop a turn, turn the object and push off it in every direction he want.
It's a nice feature for presentations. Interesting would be:
- interactive auto rotate in all directions
- interactive auto rotate limited for horicontal push off direction
- classical autorotate, that start after .. seconds after last manipulation
Ciao,
Micha
