Star Tetrahedron Wind Spinner

A sudden inspiration woke me in the night and I suddenly could "see" how the Merkaba might function as a wind spinner. I had been trying to think how I might animate the shape,make it spin in some way ,but motorizing it just seemed to defeat the point. So here is a solution utilizing ambient wind. If you look closely you'll see I've left a face off of each of the middle tetrahedrons rendering them sort of triangularly cup shaped thus catching the wind and causing the form to spin. It's an odd shape for a turbine ,but it does work...
