This paper automata entitled “Nervous Owl,” from the folks at cool4cats, shows an owl with its head turning around and back again trying to keep its eye on a motorcycle-riding mouse down below its tree. The whole mechanism is controlled by a crank below the piece that the user can use to set the animation going.

Cool4cats has the kit for sale on its site with detailed instructions on how to make one of these yourself.
