Impressive hand-cranked marble run video

Check out this video of Michael Shulteiss's marble machine. This thing is incredible. It has some of the expected ramps, flip-flops, and funnels. It also has much that is quite unexpected like the catapult-style lifting arm, a 'marble pump', a wooden chain elevator, and wood gears with holes in them that receive and lift marbles. It looks wonderfully well-made and makes a satifsying clickity-clack sound as the handle is turned.
