The Radius Music is an autonomous revolving machine that reads a distance value in real time between itself and other objects in the space. If there are no objects to alter the conditions of the space, the device will read the distance of the boundaries of the space. This device rotates slowly while scanning the room, and takes the radial distance and outputs it as a sonic frequency and a corresponding visual score. The sonic frequencies are tones and pitches that relates to the distance between the device and the secondary object. The corresponding visual score is a potentially infinite composition based on the idea of the circle. Along with Processing, it was built using Arduino and PrueData. This device was created by David Young, aka Henderson, who also conducted many other experiments using processing. The link below will bring you to his website.
