Animated monkey

As you can see in the photo of the monkey under construction he sits on a circular ply board that is attached to a bar the other end of which runs in a gear-driven eccentric self-aligning bearing which rocks him with a circular motion. This motion is continuous and draws attention to him. If a coin is inserted into the slot he raises his hat, wiggles his feet and raises a notice from a slot in the base which says ‘Thank You’.
