Found in the MAKE Flickr pool: Canberra circuit bender and MAKE author Brian McNamara‘s cool noisemaker.

This unit makes a huge range of strange noises. You start by setting the controls on the top of the unit, this sets up a sweep on the LEDS, by moving the LEDs around the light sensors a basic noise loop is set up. Combinations of frequency, volume and the two LEDs make for interesting sounds.
