A laser spot bounces on a figure being drawn on paper, trying to escape the labyrinth of lines. There is no camera nor projector; this is an experience where the audience can touch and interact with a beam of pure light – and even play a pong game with bare hands. The quality of the laser light, and the fluidity of the motion makes for a very unique experience. The piece is based upon a 3d tracking technology developed earlier in our lab, using a laser diode, a pair of steering mirrors, and a single non-imaging photodetector called the “smart laser scanner”
