Who says geeks need USB, batteries, or plugs? We love green power, too, specifically when it's powering something as groovy as this Solar Disco Ball. This party-starter houses a solar cell that converts sunlight to electricity, which converts idle feet into dancin' feet.

For $35, you can get one, get down, and get on with your bad, green self. Something so smart and fun kinda makes that USB Owl even more of a bomb.
