< #Hi George,
< 
< #Here is the code for PyMandel.py... the simple Mandelbrot
< #generator in python.  If you don't have psyco installed, you can
< #comment out those lines.  Psyco is recommended, though, because it
< #does speed up the execution time.  Uncommenting the "extra"
< #glColor and glVertex lines makes for some pretty pictures!  I know
< #inverse iteration would draw the outline much faster, but would it
< #be as colorful?
