dc fractals

http://groups.yahoo.com/group/concatenative/message/1775 - start up dc and
copy/paste the two examples into the command line.  Well, I was impressed.

(Hmmm.  This may be a subscription only link.  Here's the relevant text
from Nick Forde's email:

Here are a couple of my very old scripts which illustrate what is
possible. The first draws a Mandelbrot set and the second Sierpinskis
gasket.

(and if you're on windows, well, dc is in cygwin (but not installed by
default - I just had to add it...))
