The concept car work of BMW with their GINA Project is fascinating - moveable, flexible, adaptive skin for a car. I have been commenting for a while that the metal skin we are using on cars seem like a strange choice in many ways - particularly the finish. Anyhow this whole design is about the ability of a car skin to be more like fabric defined by underlying structure than its own rigid shape.

Pay close attention to nice details like the headlights opening and closing, the operation of doors, seats and the bonnet. It is great to see BMW not just having the idea, but going far enough to have it looking live. [More info: Geekology, WorldCarFans, Drive]
