I just published a Shopping Cart Demo for RIAnimation. It is a standard ASP.NET application with Animation added via the RIAnimator control.
Check out the live demo here: http://labs.hushhushmedia.com/rianimation/demo/
I hope to be releasing RIAnimation Version 1 within the next week or two. It is pretty stable and only needs some fine tuning. I also want to finish the MassRIAnimator control for this release.
