This is a video of an all wooden machine made by a 70-year old man named Del who may or may not be Santa Claus. It contains absolutely no metal whatsoever and displays virtually ever method of mechanical motion, all in a single machine. Sure it doesn't actually do anything, but who cares, it's freaking awesome. Santa even used a variety of different wood to make the thing, including: maple, black walnut, pine, oak, cherry, hickory, and morning. Wow!
