Wooden Binary Adding Machine

This is pretty cool. This guy apparently does a lot of wood work and has built an adding machine made of wood that uses marbles. Here is a blurb from his website:

The core of the invention is a modification of the divide by two flipflop to retain the marble that falls off the right side, and keep it until the flipflop is flipped to the left by the next marble.

He's provided an explanation of his work here:Binary marble adding machine.
