Easing Functions

I had never used a tweening library with easing functions. I had used my own easing function before but not a library. So I threw one together, made a small sample to test it. Turned out better than I expected.

Very handy. Ideas for next version: allow control points of the bezier curve to be moved; generate a javascript function (for those of us who want to run the animation from within javascript completely).

It would be neat if they included the elegant easing equations themselves. IIRC they're usually based on Robert Penner's work in 2001.

I love this. Would be handy to include examples of when particular functions map well to specific types of interactions.

The contrarian in me wants to say that if you want to make something move like a natural object, just make a force diagram and derive x(t) from first principles. This is neat for visualizing other easing functions, though.

I expected that clicking on a easing function would use that function to transition to its detail page. Instead, it uses what looks like easeInOutQuint for all of them.
