I see that one of tutorials on the Cartoon Smart site shows how to turn a face. I don't know if it shows how to do a Exorcist move and rotate the head though.

Then again if you want to start producing 3D flash animations you may want to look into http://www.swift3d.com/.

I too remember someone posting a tutorial on this subject. I would check out the Lost Marble site or the Toon Boom site. Then again it could have been the Cartoon Smart site...
