I've been juggling with the newton fysics plugin of the AnimationMaster.
Rather funny to see objects in a free fall scattering around, or a flag waving.
After setting up a scene it's possible to use computer dynamics to calculate all behaviour of objects,
and export them to 3ds or obj and so on.
So I made a Quake flag to use in my maps.

When you like it you can download a map called qflag.zip
in models with example on quaketastic,
but for that you have to log in.
