animation framework


I wonder if Rails is already or planning to get integrated with an animation framework? It may be a javascript library or some runtime environment like flash has.

I know a bit about but besides its animated effects, I dont see any animation library which we can use to animate anything on the page with an effect. I think Yahoo UI has animation library but I dont think rails developers use Yahoo UI so much.

I almost always have to use flash for the animated part of my rails pages and that makes me feel uncomfortable with the actionscripts and flash environmental things.

thanks to everybody
