Sailboat in a Storm Kinetic Sculpture - Etsy

Anyone that knows me, knows that I am a sucker for a classic style kinetic sculpture with simple mechanics. Etsy shop kelleratelier has only one item listed and the description reads: "A homemade kinetic image-the crank is turned at the bottom right in the frame, the rough sea gets in motion and the boat weighs itself in the waves. Waves and boat are set to move separately via a crankshaft." I keep coming back to look at the boat.
