Sound Sculpture is a playful synesthetic installation where the user activates sounds by touching thin air.
A Microsoft Kinect sensor detects the user's different body parts in space, and creates a virtual body in the simulated virtual space. This ismulation has different objects floating in it, not present in the physical space.
When the real life user moves causing a collision in the virtual space, these floating shapes emit distinct sounds, allowing the user to mold the different shapes in space with this new sense of touch.
Sound Sculpture features no visuals at all, that's why photos of it simply look like people being weird in an empty room.
