Created by Matthias Wandel, this nifty machine uses marbles as a counter of sorts. Video after the break.

The retention of this extra marble allows the state of the marble accumulator to be dumped. The adder would just as well add without it, but the number would have to be read off by the angle of the rockers, rather than have the device dump the count out
