Spinning planet

I love my Mova Globe. This is a globe that slowly spins without batteries or wires. Its silent revolution is powered by ambient room light, and it will spin forever even from the light of a desk lamp. Internally there are two layers, the visible layer which spins inside a seamless clear shell, which sits on a clear tripod. Mova comes in 5 sizes, and 5 different forms, such as Mars, Moon, a map Earth, or a photorealistic Earth. I have the 4.5 inch (19 cm) version of the realistic Earth which spins next to me as I work. It is drifting right now. Since it isn’t cheap ($218), it makes a great gift for the right nerd. — KK
