WMMNA tells us of the Circular Optical Object Locator, a light-based music box of sorts created by David Merrill and Tim Hankins. A transparent disc sits above a group of six colored lights, each able to represent a different sound or instrument. By placing opaque squares on the disc and rotating it, a video signal captured by an overhead camera is transformed into the appropriate sound based on what light it sees. Move the squares closer to the center and the pitch might change. Video and more pictures await you on the project’s site.
