Radically novel materials change shape by 100s% following temperature or illumination changes. Such sophisticated response suggests different ideas for deploying such materials from in conventional mechanics and devices. We describe the materials and new mechanics paradigms to exploit their novelty: Local material shape changes can be arranged so that intrinsic curvature is induced into flat spaces. I will employ many demonstrations, and re-examine the map-maker’s problem of resolving planes with curved space.
