Algodoo

One of my first scenes that I've put some decent effort into...
Doesn't run on fuels and or lasers and or collisions. (Yet) >:D
I think I'd like to try running it on collisions since it has more
potential rpm wise.... Lasers would work well for this right now.
Don't push it past 350 rpm right now, the long valve arm will
glitch out and you'll have to move it back when the rpm is lower.
EDIT: Added Rocker Arm stops and changed a few densities.
Should run up to 450 rpm
