Fireflies come alive in this art installation controlled by Raspberry Pi

Making it’s debut in the Olympus Photography Playground in Vienna in February 2015, Neon Golden’s art installation “Swarm” mimics the behaviour of fireflies via LEDs which are strung from the ceiling at various different heights. Using both Raspberry Pi and Arduino control mechanisms, there are motion sensors which detect the movement of visitors and trigger lighting changes according to code which is based on the Boids algorithm by Craig Reynolds. It looks absolutely stunning and apparently really drew the crowds in at the OPP. You can see photographs of the build and the results on Neon Golden’s website. You can see more photographs on
