ODE (like most simulations) won't behave nicely with variable
timesteps. You could try running the simulation at higher rate than
the drawing; or run at lower rate, and interpolate the frames to draw.
Make sure the simulation is light enough to run properly in every
machine, and adapt the drawing rate.

See http://www.gaffer.org/game-physics/fix-your-timestep/ and the
Fixed Rate Pig from http://olofson.net/mixed.html
