Holograms record and display realistic three-dimensional images that appear to float over a surface. One day they might be used to immerse viewers in virtual worlds or simply provide ultra-realistic video calls—that is, if the holographic images could be made to move. Now researchers have created holograms that display different two-dimensional images when stretched (Nano Lett. 2017, DOI: 10.1021/acs.nanolett.7b00807). Although they can only switch among a . . .
