Shape matters: Changes, which are brought about by irradiation, to the properties of a medium have been of immense interest not only in terms of basic science, but also for applications such as data storage media and molecular devices. In the light of a recent publication reporting a photodriven liquid to liquid crystalline transformation (see figure), an overview of similar transitions is presented.
