There have been a lot of innovative applications for OLEDs lately - Ingo Maurer’s Double C-Future chandelier, Tom Dixon’s OLED flat lamp, and now Jason Bruges’ Mimosa, a dazzling piece of art that uses Philips OLED lumiblades to form flower-like light petals that open and close in response to onlookers. According to Bruges, “The piece was inspired by the Mimosa family of plants, which change kinetically to suit their environmental conditions.” It’s also currently on display at Superstudio Piu in Milan, Italy if you want to check it out first hand.
