Project #49 Binary Marble Counter

There are a few of these kicking round the internet but they all seem to link back to Matthias Wandells excellent machine. I took a stab at making my own machine from easy laser cut parts. 2 rows of numbers at the top hold each of the digits to be added at the same time, the rows can be dropped individually at the output held. Some work needs to be done to capture the overflow digit correctly (although that could be done with a fifth flip flop gate). (file needs fixing)
