A Kinetic Sculpture by Los Angeles sculptor Bruce Gray, titled "Califormia Dreamin"
One of things I am always excited about in a work of art - is a sense of motion. But with kinetic sulpture - you have the immediate delight of motion in three dimensions rather than motion hinted at on a flat plain. This sculpture also has sureal sound effects, even though it doesn't seem like the Califormia Dreamin of that era.. Another thing I like about it is the idea of alternate routes that all lead to the same destination and the juxtaposition of natural force (gravity) and man-arranged force which lifts the iron ball to the top for another cycle.
I found this video featured on a blog called DenverArtsyGal - she has a fantastic blog and twitter feed so take a look.
