Rotation Source Code Argh!

Finding source code for nice image rotation is proving more difficult than I thought... I have something that will work if I tweak it a fair amount which should be fine but still, you'd think I wasn't the first to want to do this.

What would have been nice would be to successfully implement the Quicktime VR stuff but I can't get the demo because they e-mail out the links and I've yet to receive an e-mail either through Uni mail or my personal mail.  I'm not impressed with their site as a result.
