Good custom tween class?

Hi people,

I’m working on a project right now that requires small bits and pieces of tweening. I’ve got complete freedom in the animation department, so I’m trying to come up with some tween effects that are both stylish and crazy at the same time. The tween class that comes with Flash is a bit limited though.

I’m looking for some good alternatives to the standard Flash tween class. Some stuff that would be nice to have are delays on tweens (start x seconds after the tween is called) and maybe the ability to tween colors. It’s not a requirement, but sure would be nice to have.

Looking forward to your suggestions!
