The “cocoon light structures” that Israeli-born designer Ayala Serfaty creates don’t look like anything you plug into a wall. They look more like organisms that glow. Using thin, transparently tinted lamp filaments as “glass veins” that create both depth and surface, the tubes are then sprayed with a clear polymer in thin strands, connected like a spiderweb around the tubes, to generate “a skin-like crust,” or what Serfaty has called “a membrane of sorts” that feels like a soft cocoon. (In fact, the process was developed in the late 1940s by the U.S. military for cocooning ships.)
