Circuli - Generative Ambient Sound Instrument
25 Feb 2012- 
    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. 
- 
    The envelope of the produced sound is determined by a number of parameters including final circle size and time of interaction between two involved circles.
