"California Dreamin" Rolling Ball Kinetic Musical Sculpture (The movie)
"California Dreamin " (81x50x32) by California sculptor Bruce Gray is a motorized kinetic ball machine sculpture with 2 steel balls that get lifted by a drive chain conveyor system. The balls have 3 tracks to follow that are changed each time by 2 switches, or as I like to call them "gravity operated, magnetically optimized, switching units." One of the switch ideas actually came to me one night in a dream, after several days of trying to come up with a suitable design.
"California Dreamin" is part of a private collection. A similar motorized ball machine can be commissioned for around $15,000 and up.
