[ODE] A 'real' demo of ODE

Cool demo. However it crashed the 1st time i started it. =P The other runs
were fine though.

It would be ideal if you could set some sort of 'safe-time' on a per body
basis, which would determine the simulation rate for the stepsize for a
particular island. This would require a change in the way ODE works though,
as the collision detection would have to be redone between steps as well.
Have you ever been thinking about this Russ?

I'm pretty interested in these. Our suspension isnt as cool as yours. =( I'm
wondering how have you implemented them? As a true ODE joint?
