Hi Kirby,

it's fine that you "host" a slightly amended version of chaos.py
on your website.

The original file is part of the demo that ships with Python and
the turtledemo has been moved into  the Lib-directory of the
standard distribution.

Some of these demo-scripts suffer from (more or less minor :-) )
quirks or deficiencies and could be amended in this or that way.

I think that such amendments should go into Python 3.3. So if
you or anybody else have any ideas, complaints or - as shown here -
propositions or results, please let's discuss them, so the turtledemo
can obtain not only a demo- but also an enhaced educational value.

Best regards

Gregor
