This offering from Crazy Case is exactly what you could have asked to get your nerd cells ticking. Haters might call it impractical, but you know it is awesome, especially when you get to see it in action. The DMC-12 has amazing detail with lights and wires that glow when you get a call or notifications.
Front wheels are considerate enough to swing apart to allow the user access to the camera, and the volume buttons. It is priced at 5940 yen, or $50.
