	While Lorenz had his first insights modelling weather, the famous
`Lorenz Attractor' is a model describing boiling/roiling water.  The story
of his discovery can be found in that `Chaos' book by Gleick.

	BTW: FRACTINT.EXE has come up on this list a few times.  I believe
the latest version is 19.2 and has a new and improved Zoom feature. It
(and many cool and groovy things) can be DL'd from the Fractint WWW Page
at:
	<a href="http://spanky.triumf.ca/www/fractint/fractint.html">
	Fractint homepage</a>
	
	Anyone interested in playing with Chaos (why else would we be
marxists?) should keep this powerful -- and free -- tool on their
harddrives...
