Cool Mouse Effects - Suggestions?

Hey all… this is pretty urgent, so I would severely appreciate any helpful suggestions you can offer.

I’m working on a website in Flash (duh), and actually I have the file open right now. I’m just giving it a few finishing touches, but I need some kind of cool user-interactive mouse effect.

I was thinking along the lines of a circle (or other random object of my choosing) which follows the mouse around, and has a spring kind of reaction when it actually catches up to the mouse. There was a tutorial on springs but I must have done something wrong because it wouldn’t work.

If anybody has any other suggestions for this, or could help me out with my current problem, I’d greatly appreciate it. Thanks.
