A mobile has mobile elements made from a solar cell, a hollow beam and a motivator. The solar cell is mounted to a substrate and connected via wires through the hollow beam to the motivator. The hollow beam supports the substrate at one end and the motivator at the other. The motivator may be a small electric fan or valved gas jet. The substrate is a flat plastic panel, such as a CD-ROM disc, a lightweight plastic sheet, and printed circuit board. The mobile elements may be connected as in a traditional Calder mobile, or in an aligned vertical stack. As the solar panels receive sufficient light, power for the motivator is generated, causing the mobile elements to move.
