David C. Roy makes wooden Kinetic sculpture in Connecticut. Kinetic sculpture is one that moves through the force of wind, solar or with a touch of the hand. Roy's works are wound (think of a music box) and then continue to move for various lengths of time -- some as long as 24 hours.
Kinetic sculpture is absolutely fascinating to me. Art that moves. Interacting with art (as opposed to simply viewing art) is something I would love to explore in the future.
