For the most part, our wood and carbon fiber objects are solid, inert, and boring lumps. They don't bend or curl—or at least, they aren't supposed to. But MIT researchers have created wood and carbon fiber specially designed to be dynamic, conjuring up visions of wood furniture that self-assembles out of the flat pack or carbon fiber that morphs with the temperature.
