	About a year ago, the company I work for acquired a multi-
million dollar digital imaging department and I set out to create the
biggest fractal in the world (or at least the biggest one I have ever
seen...)  I wanted to be able to blow it up to 40" X 60" an not see
any pixelation in.  This meant a resolution of at least 150 dpi so
after I found the portion of the Mandelbrot set I wanted to do, I
started crunching a 8,000 X 10,907 pixel fractal.  Using my own
Home Grown software, I did it in parts, because this thing took
over 400 hours to crunch on my 75 Mhz pentium.  I couldn't tie up
my PC for that long uninterrupted, so I made the program such that
I could stop the crunching at any point, then pick it up later when I
went to bed.  I had no idea what the color palette for this monster
was going to look like while I was crunching it.  Therefore, rather
than writing a file which contained color information (such as a
GIF, TARGA, or JPEG) I wrote a file which contained iteration
information.  i.e. each pixel in the file was represented by the
number of iterations required before the crunching loop bailed, or
maximum iteration was reached.  Max iteration BTW was 65,000.  
   	After the crunching was complete, I worked on the color
palette.  I wanted 24 bit color so the change in tones would be very
smooth on the final print.  The final Targa file (chose that because
it was very simple to write with only a 18 byte header) was
approximately 260 Megs. 
	I named this image "Primordial Chaos because it seems to
be surging with energy.  Let me know what you think.  I'd be glad
to give anyone the software I wrote to create this if there is an
interest for it.  
	Here's a smaller (Still, big tho.., 1 Meg) version of it.
