We present an interactive process for experimenting with complex light effects produced by reflective objects at the scale of a room. The reflective object scatters the light of a single projector into a complex pattern on all walls of the enclosure. The user/designer of the space is able to intuitively manipulate the scattered light by rotating the reflective object by means of an Arduino-powered servo and infrared hand-tracking with a Kinect. Our software maps the relationship between a two-dimensional projected image and the servo’s angle of rotation onto the three-dimensional coordinates of the designer’s hand, and it’s through this mapping that the designer can exercise some control and precision over the location of the unpredictable light effects.
