Crystals are usually thought of as rigid and brittle. Yet some molecular crystals can bend, jump, twist or even change shape when exposed to light. Understanding how tiny molecular movements inside an ordered crystal can produce such large visible motions is an important challenge for developing responsive materials that could eventually be used in actuators, sensors and other miniature devices.
