I started to experiment with “video feedback” and soon got fascinated. This video shows an example of the intricate patterns that emerge when you point a camera at it’s own picture. There is really no processing or fancy electronics involved, just feeding the picture back into the camera and watching how it gets replicated over and over again.

Flowing sand in this exhibit is just a tool to simulate “Voronoi Cell growth”. Believe it or not, hundreds of patterns we find in nature can be constructed using this simple geometric rule. The video shows voronoi cells growing into a honeycomb pattern…

I am one of the lucky developers who gets to invent new hands-on and body-in exhibits about geometry!
I am keen to hear about anything geometry related that fascinates you! Games, sculptures, architecture, classroom activities, online content, puzzles, books… please email to sebastianm at exploratorium edu.
