Lexon’s New Gadgets Brought To You By Corn, Bamboo, and the Sun [Green]

Lexon recently announced a new line of sustainably powered gadgets that are decidedly down to Earth. That is, they're made from bamboo and maize bio-plastics. And let me tell you, corn has never looked better.

If you're in the market for a new calculator, alarm clock, or FM radio, why wouldn't you want it to be made from corn and bamboo? Especially when it looks this handsome.
