Firefly is an interactive lighting installation by french designers Kkristen and Vincent Moreau. It’s currently presented for the first time at Shanghai World Expo 2010 as a part of lighting design of the Urban Best Practices Area.

Firefly reacts to human behavior like a swarm of glowing insects. These ones change their appearance in human presence : they wriggle, light up and scatter in response to the motion of visitors around. The cloud alternately disperses and merges… and its shape evolves to take a different appearance, again and again.
Firefly is an invitation to play, in search of a sensitive interaction between man and his environment.
