CSS3 Transitions with Javascript Fallback

Question

Is there a javascript framework out there that will use CSS3 Transitions for effects like changing opacity or moving elements but will fall back to using javascript setInterval/

Answer 1

sadly none of these alternatives seem to allow you to use the easings, like bounce.

My attempt to use animate-enhanced moved the element an inch and then just removed it. I really would like to keep the bounce instead of just a cubic or linear easing.
