Hi Jeremy,

I just wanted to point out that Python also has a turtle graphics 
module: turtle.py
While turtle.py in Python 2.5 did a good job, it has somewhat limited 
capabilities. It will be replaced by an enhanced one from Python 2.6 on. 
This enhanced module (fomerly known to some of us as xturtle.py) is 
already part of Python 2.6 beta2 and I'll do a more elaborated posting 
on it as soon as beta3 is out, which should happen these days.

The new turtle module has - as one of it's new features - enhanced 
animation which is intended to serve as a visual feedback facility for 
young programmers. (Moreover they can - if they wish - choose the shape 
for their turtles, for instance they can use turtle-shaped turtles or 
design their own shapes ...)

The new module will also run unaltered - as is - under Python 2.5

You can download it from here:

http://svn.python.org/view/python/trunk/Lib/lib-tk/

The docs can be found here:

http://docs.python.org/dev/library/turtle.html#module-turtle

Regards,
Gregor
