Rolling Ball Sim

I've wanted to do a mechanical computer for a long time. I have a few mechanisms in mind that I think will get me far enough, but I would like to be able to test my ideas quickly. I can do a 2d simulation that runs almost as a cellular automata. Simple rules like a ball will fall the the square below it. If that square is a a ramp, it will be deflected.

• Ramps
• Camps
  • Active / passive
  • gaps
  • ramps
• Signals
• Source
• Levers
  • Flip-flop
  • memory

Try building the binary adder first.
