I tried some larger grids of masses with my simulation system. It of
course takes much longer, several hours on an Athlon 1 GHz.
ball_sim10.mpg shows what happens if you decrease the connection stiffness
too much. The grid is not self stabilizing under extreme deformations.
Adding 3d diagonal connections might help, but this would slow down
calculations even more.

sim9 - 'crump'
sim10 - 'flumpfppfpfffffff..'

This is all very impressive, but I'd rather see a regular box dropped,
or a dice or similar, which doesn't deform. Oh, and something which
isn't cubic would be interesting too! :)
Few things we know from our everyday behave like gel...

If you want to do some bigger things like this you'll have to port your
scripts from SDL to something faster like C/C++ or something else.

I really like this. Again, it would be interesting if you replaced this with
a mesh so we could see the box shape more clearly. I really like #10. That's
what I expected to happen to #9. :)

Or in the case of a 4x4x4 grid: 6 bicubic patches. Should look fun... :D

More complicated shapes are just a matter of creating their starting
geometry, no deformation at all is impossible with this approach, few
deformation usually requires accurate computation but I will try something
like that.

I know, but i would lose the possibility to rely on POV-Ray for generating
the enviroment collisions when having a separate program. I probably will
wait until i get the source of POV-Ray 3.5 and make a patch...

I'm working on that, it will also be helpful for collision calculations to
have the outline mesh.

#10 won't look so good with a mesh. If you look closely you'll see that the
most contorted part of the cube becomes inverted (inside-out).
