MochiKit.Animator: New Animation in MochiKit:

“MochiKit.Animator is an enhanced*, fully vectorized version of Bernard Sumption’s animator.js. It eschews the use of classes and instead uses composition to build complex effects in one or two lines of code. The idea is to have everything work “right”. This means not having to specify start values, maximum efficiency during playback, and clean, automatic animation reversal. In other words, the goal is to make an animation library that doesn’t suck.”

Interesting package
