Wood Binary Adding Machine

This is so cool. I love hands on math that this neat video of a wooden binary adding machine represents. My father made me a set of Napier “Bones” which I still cherish and I have used wooden tablets with stone counters for adding Roman Numerals and an abacus just for the tactile experience with mathematics.
