You can try the Bouncer demo posted on our downloads page (top of the list):
Also posted is "Lemmings", a drag routine that affects multiple objects and
makes for a drag effect with a very organic/lifelike feel. This was modeled
after a Flash project I disassembled, and while I don't have the math quite
right (Richard Hertz, where are you?) this is quite a fun little stack.
Personally, I've always thought there should be more "porting" of other
behaviors/effects from other development platforms (Flash, Director, etc)
and would encourage folks who have the inclination to do so and share with
