Kinetic wind driven artform sculpture, graceful and elegant

I think this Kinetic wind driven art-form sculpture is beautiful and could even be retrofitted with a micro energy harvesting system that could supply low energy lighting to the piece or even to exterior patio lights as an example. Graceful and elegant indeed.
