Amazing Wooden Machine Video with No Metals

With the exception of Brad Litwin's piece entitled Extra-Universal Movement, I don't know if I've seen such an elaborate hand-cranked wooden machine. This gentleman has constructed an amazing device using only wood and glue -- no nails, no screws or ball bearings. It is quite an achievement. It is my sincere hope I'm doing things like this at 70 years old. Bravo!
