Lol this is wild. ScoreLight is a prototype musical instrument capable of generating sound in real time from the lines of doodles as well as from the contours of three-dimensional objects nearby (hands, dancer’s silhouette, architectural details, etc). There is no camera nor projector: a laser spot explores the shape as a pick-up head would search for sound over the surface of a vinyl record – with the significant difference that the groove is generated by the contours of the drawing itself. The light beam follows these countours in the very same way a blind person uses a white cane to stick to a guidance route on the street.
