"Let the material do the talking" is one of the ideas behind GINA, BMW's concept sports car. Instead of a metal body, it has one made from stretchable material. Thus, designers don't have to worry about, say, smooth continuity between the wheel wells and the body -- the material naturally takes care of a flow. Also, the car's headlights act and look like human eyes, blinking open and shut as needed. GINA stands for something like "Geomety shape functions In N Adaptations."  http://www.youtube.com/watch?v=kTYiEkQYhWY
