These blinking electronic badges, created for the Burning Man 2015 festival, actually evolve and change every time they meet another badge. By the end of the festival, each badge had a completely unique color pattern.
Burning Man has a tendency to attract extreme makers, and thus produces a lot of really interesting inventions, both technological and artistic. These Burning Man 2015 badges fit into both categories, and add a bit of biology to the mix. Designed by a maker who goes by the name "Bunnie," the Burning Man 2015 badges blink out a colorful light display. When one badge comes into contact with another, both badges change color in compliance with a code based on genetic science.
By the end of Burning Man 2015, each badge had met so many others that it had evolved its own one-of-a-kind pattern.
