When I try to run this example, I get an error and I was hoping folks
might help me understand why:
running your script as is (you can disregard the deprecation warning
as I'm using Python 2.6):
$ python mset.py

then I tried changing 'shape' to be 1000x1000 and get:

So, I put together a Mandelbrot demo if anyone is interested. I put
it (an a big description) oh how it all works up on one of the blogs
I maintain. I realize there are better ways to accomplish some of
the things in the demo code, but I was hoping you guys might look
over it and tell me I have the thinking half correct.

Next up CFD . . . ugh.
Thanks!
