Before the age of film, zoetropes created the illusion of motion by showing the viewer progressive images through small windows in a spinning cylinder. As the zoetrope spins, you see whatever images are inside move. Today, this effect can be recreated with a strobe light.

Flux, a sculpture by design students Frederik Scheve, Janno Ströcker and Dieter Pilger, who study at the Köln International School of Design in Germany, is designed to play with our sense of visual perception in the same way, without any external lighting tricks. The illuminated spherical structure, designed according to the Fibonacci sequence, rotates at a certain speed and lights up at a certain frequency from within to create the illusion of motion. It’s pretty trippy, so make sure to watch the video above in HD.
