I must say he was absolutely right. I generated these images by taking
both the real and imaginary parts of the z and c variables in the
Mandel/Julia equation

                z = z^2 + c

as independent variables to define a space of four dimensions and then
selecting different planes (2D slices) of this fractal.

The images can be made in fractint, and as someone pointed out, fractint
can draw just about anything. What I meant was that it wasn't a standard
fractal type.

I will be uploading the program I used to generate these images to the
same page I posted the images soon (give me a day or two) just in case
someone is curious and wants to look at it.

Subject: (fractint) A modified Bill Decker par

Hi, everyone--

I've finally (I think!) figured out how to work with posted pars in
Fractint.
I played around a bit and came up with this, based on a Bill Decker par
from a
little while back.  Could have been a candidate for either "Best
Human/Animal"
or "Most Whimsical".  Please let me know if this one doesn't run
OK.

Hello, folks.

I've only recently begun reading this list.  Near as I can tell,
you folks are engaged in some sort of contest to see who can come
up with the dirtiest fractal.  I admit, it's not exactly what I
expected when I subscribed, but what the heck, here's my entry,
along with a second from the same formula I just liked.  I think
the whole thing is a lovely idea, and I'll leave it to you to
decide which is which.

Welcome to the only x-rated fractal site on the web!!! Children and integers must be
accompanied by their parents.

Did I miss a category in the contest?  drat!!!! I think we ought to subpeona Les and
interrogate him about that color map he used.....it's a tripp!!!

Is Les going to have to post warnings before we can download this months posts?
<<wonder what they would say??>>

Glad you can be a part of the madness....

I think Linda has some very good guesses there......to return the compliment, I
guessed that Linda did My Latest Favorite Fractal (I haven't visited her website yet
so it's really a guess).  Other than that I had a hard time sorting out who did what.

Looking at all the beautiful entries has provided me with a great deal of

Subject: (fractint) Yet another diff_delt1 fractal

This one sort of resembles the web-tangle pars that I included in my
earlier list of pars based on this formula. There are plenty of similar
views lying around as you cycle through the functions available.

I've included a second version of the par (star-flowers4s) where I've
cycled the colors so that you can see some imperfections in the image. In
the upper-left and lower-right-middle, you can see some smearing in the
direction in which Fractint evaluates the fractal. This happens quite often
with this formula (for certain fn1 functions) and I usually hide it by
matching the color of the smear to the background areas. Most times this is
successful as you can see in star-flowers4.

I can minimize the smearing by using passes=1 rather than passes=g, but it
won't go away completely. Can some of you formula gurus tell me what is
happening? Can I fix the formula to get rid of it? Is it due to loss of
precision? I designed this formula to especially investigate the
possibilities of taking the difference of two nearly identical expressions,
so precision is a distinct possibility.

Anyway, thanks for any advice that you can give.

  It's due to periodicity checking.  To get rid of it, enter the <g> scre=
en
and type the command "periodicity=3D0".

Bill,

 - I can minimize the smearing by using passes=1 rather than passes=g, but
 - it won't go away completely.

Press G, type "periodicity=no", press ENTER.  This disables the periodicity
logic that causes the smearing.

Which formula did you want the par to use?
  a) koffset_rx=3Dry_jul   (never been posted!)
  b)  offset_rx=3Dry_jul
  c) g_offset

My mistake.  My number of formulas is getting
away from my system of naming and filing.  This
is just the same as one I posted a few weeks ago.

Subject: (fractint) contest voting and downloads

I just got done with voting and commentary.  What a herculean
task.  Of course, if I weren't so long-winded...

Deciding between all of the excellent entries was really tough.
The hardest for me, with the number of serious finalists, were:

Best Use of Color: 7
Oddest: 3
Most Whimsical: 4
Best Horror: 4
Animal/Human Shape: 5
Best Fractint: 4

I almost voted for one of my own in one category, but decided
I couldn't possibly do so objectively.  I just hope *someone* did!

Thanks again to the contest officials and entrants for the quality
of the contest and its presentation!

Two minor whines:

1. Still waiting for the parameter downloads; the officials are
 probably still recovering from the initial effort, with more sweat
 to come starting tomorrow :-)

2. Making the download work on my DOS/Win3.1 system will
 be a challenge (8.3 filenames)...


Eagerly awaiting the results,
  Bud

  It's due to periodicity checking.  To get rid of it, enter the <g> screen
and type the command "periodicity=0".

THANK YOU!!! to Damien, Kerry, and Paul for a truly splendid job in setting up
and presenting the contest! Surely you all are due some form of Fractal medal
for slogging around through knee-deep e-mail and HTML editing detritus!
Kudos and hats off!!

Big Congratulations and Thanks to all the entrants!!  I found it very hard to
vote from among such an amazing assortment of wonderful images; am having a
wonderful time viewing and reviewing all the pix and puzzling over many (how'd
they DO that)?
Thanks for displaying your works!
