This actual working solar rocker is made from blown glass. The outer diameter of the wheel is 11 inches, and each small sphere is 3 inches in diameter. Two, twenty-watt halogen bulbs illuminate each sphere, and the rocker period can be adjusted from 15 to 150 seconds by sliding a small weight along one of the arms. The center of the rocker rolls on a tapered rod.

     The entire mechanism is completely silent, and self-starting. Note how the rocker shifts and projects shadows on the far wall.

     The "mani" solar rocker lamp is available for sale at talusfurniture.
