should really be reading physics for my examns but couldn’t resist blender… so I started a sort of spring python script few hours ago… I say boing… what say you?
first test ->

Looks pretty good, but I think maybe the object should stay on the ground for less time.
cool, I’m learning python (along with 1/2 million other projects), someday I’m gonna make cool things like that. 
That’s pretty good! I created a python script for simulating springs too. It’s called Tangix- Elastic gravity simulator. You can download it below to see how I got it to work. It’s not that great, and you can’t really reset the script without reloading your .blend file.
thanks people!
well the ball animation wasn’t really the point… the twig in it was the thing…
RipSting: Yea I’ve tried your script before and it’s way cool! And with the fiber script you are like a blender python god or something! mine is still a very crappy thingy but maby will come to something more… 
That looks pretty groovy! Really organic looking movement with that boingy-thing 
Holy crap… you’ve made a soft-body script! Now how about collisions of 2 or more soft body objects
