traer physics library for supercollider

a while ago i started porting the java/processing library TRAER.PHYSICS 3.0 by Jeffrey Traer Bernstein to supercollider. it's a simple and elegant particle system and a physics engine all in one. there are already ports to actionscript3, javascript and c++ (cinder), but i haven't seen anyone working with it in sc yet. so i had a go - both to learn more and to have an alternative to my own physics library quark redUniverse.
