Twin Cities Maker recently participated in a local art festival, bringing with them three projects that had been created by members David Bryan, Riley Harrison, Cali Mastny, and Aaron Prust. Among them was Strange Attractors, a 6×4 panel of addressable RGB LEDs controlled by a Raspberry Pi microcontroller. The matrix is designed to mimic the flashes of fireflies, which tend to synch with other fireflies’ patterns, but also change their patterns based on ambient light. Visitors were invited to shine a flashlight on the matrix to see how the art reacts.

The project’s technical writeup hasn’t been published yet, but the team has posted its Python scripts in Dave’s GitHub Code Repository.
