You can listen to the original excerpt on Youtube from American String Quartet.
In the course of developing the piece, I made some shortcut/extensions to the Pattern class, which can be found here: gkcPatternExt.sc.
Update: This piece has been accepted and published in the livecoding-focused DVD accompanying the Winter 2011 Computer Music Journal (Volume 35, Issue 4). The program notes were available at the time of this update. Links to some are posted on this TOPLAP wiki page.
