jsTransitions - Visualization of easing equations

Why JavaScript animation library authors don't like writing demos?

For example, scriptaculous show demos of different types of effects, but it is only a little bit of it's power. jQuery demos arouse no enthusiasm too. moo.fx demos look very poor, although this small library can do nearly any effect you need, regardless of it's small size.

I wrote a simple demo - just for showing it to my designer - visualization of Robert Penner easing equations (irrelatively to any library).

Hope, this will save somebody an hour or two.
