Cut to Ribbons
Projector-based interactive installation artwork. Inspiration came from the ribbons used in rhythmic gymnastics and chinese ribbon dances.
By using multiple cameras to track the 3D motion of a distinct object (such as a torch) held by a visitor we can create and project a virtual ribbon, with the dancer and ribbon dancing on opposite sides of the virtual/real border.
The images and videos below are best watched with anaglyph 3d glasses (there are versions for other display techs) in fullscreen, but you'll get the idea without them. Part-way through the 'light ribbon' video you'll see what the cameras see.
