Stored here for posterity's sake it was found on http://hcc.cc.gatech.edu/documents/230_Edwards_swing-sampler.py
and the nature of the web being what it is who knows how long it would be there or if I could find it again.
This is exactly as I found it. I have verified that it works with Jython 2.2 with Java JVM 1.5 & 1.6 and based on the code I suspect it would work with a 1.4.2 JVM
