Kikkerland Solar-Powered Rainbow Maker
This solar-powered rainbow maker from novelty company Kikkerland is a neat way to add a touch of magic to any room with a sunny window. It suctions onto the glass and uses the power of the sun to slowly rotate the crystal pendant hanging below, sending colorful streaks of light around the room.
You can watch the internal mechanisms work through the device's transparent housing, which is fun, and if you have a pet who stays home alone most of the day, they're likely to be entertained watching the light patterns play out along the walls. All in all, a unique little addition to your space, and makes a great gift besides.
