Social Firefly is a reactive/interactive installation made from intelligent lights that influence one another. It was created by Jason McDermott and Liam Ryan (Arup) with Frank McGuire for the Vivid 2011 festival in Sydney.
“Social Firefly is a demonstration of how interaction design can be dynamic, beautiful and playful, as well as teaching us about our relationship to other creatures with which we share this earth. Inspiration came from lateral and cellular communication systems such as those used by fireflies in synchronizing their rhythms and slime molds in movements through caves, which collided with network theories and cascading relationships between the parts and the whole. These were then shaken together with the Vivid 2011 theme of Fiat Lux and user centered interaction design to create the light installation that is Social Firefly.”
