Hi,
for more looping examples, check out the livelooping channel on youtube:
http://www.youtube.com/watch?v=mK-_bhpeesQ It was started by Matthias Grob, one of the pioneers of live looping and inventor of the Echoplex digital pro, one of the most powerful looping devices.
I'm looping my Stick quite often, "The Four Ages of Sand" on my Myspace page is an example of a looped Stick piece.
