Interactive designer Toke Oliver Barters (DK/UK) has developed the RGB Player (RGB stand for red, green and blue), a musical instrument that scans objects’ forms and colours and turns them into music.

You just have to place on a rotating glass disc any colored object, its colour value will be translated via the built-in scanner into sounds that vary also according to the distance of the object from the center of the dic (the closer to the center, the higher the pitch)
