was looking
at his website earlier this afternoon and tracked down a very cool
article
of his that seems to cover much of the same stuff--i think it does

annals of
the new york academy of science no. 999 (2003) pp. 322-363. it's
available
through wiley interscience, if you have access to that database.
i could
put a copy on the wiki if access is a problem, but monday.
