Observing natural growth is mostly a slow affair, but these kinetic sculptures illustrate the process in a brief moment repeated over and over. Jessica Rosenkrantz and Jesse Louis-Rosenberg, who head up generative design studio Nervous System, created the tiny sculptures in the form of 19th century zoetropes made using modern 3D printing tech. Composed of multiple evolving sculptures, when spun and illuminated with a strobe light the complex forms jump to life.
