Circuli

Circuli is a generative sound generator that helps you create ambient sound scapes to listen and have fun right in your Mac OS X Dashboard.
Main features:
-Circles grow at a constant rate.

-No two circles can overlap.
-Bigger circle pushes and shrinks smaller circle when in contact.
-A circle “pops” and makes a sound when its boundary intersects with the center of another circle.
-The pitch of the sound is determined by the position of the circle on the background. Bigger the hole, higher the pitch.
