This little rainbow machine will fill your room with sparkling colors that gently swirl around you. And unlike simple sun catchers, it uses the sun's own power to turn the genuine Swarovski crystals hanging beneath for a stunning dance of light. Designed by David Dear for Kikkerland, it mounts to the window with a suction cup and features colorful gears you can see moving as the two large crystals turn in opposite directions. About 5½ inches high.
