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
• Cams
  • Active (responds to signals)
  • passive (pushed by other cams)
  • gaps
  • ramps
• Signals
  • Generator
  • Sensor
• Source (from signal)
• Levers
  • Flip-flop
  • memory
  • Weighted
• Teleporter (this lets us simulate multiple dimensions)
  • In gate
  • Out gate

Try building the binary adder first.
