Miniature Kinetic Sculpture
Many people have asked for a smaller kinetic sculpture and David hasn't created one. He has found that the rhythmic motion is lost if you decrease the mass of the pieces. He especially dislikes his designs if the are jerky and strives to create mechanisms that produce a fluid, smooth motion.
But that doesn't mean others haven't created tiny kinetic sculptures, almost jewel like in their detail. Here is the work of Polish sculptor Szymon Klimek. Not only is it tiny but it is solar powered as well! And it is housed in a wine glass.
