The MiTree concept consists of two interactive sculptures situated in Kendall Square in Cambridge, Massachusetts. Both trees sense the sound and movements present in their environments, and process them to create melodic visual and aural displays. The "Air Tree" is inspired by the notion of the "whisper chamber" which carries sound between distant points. Instead of carrying sound across distance the Air Tree carries sound across time, releasing a series of melodic tones generated from previous sounds it has heard. The "Light Tree" is a visual message board. The motions of passers-by cause text on its display to flutter away as if caught in a breeze. In collaboration with OJ Studio.
