Classic FOTD -- February 18, 2001 (Rating 7)

Fractal visionaries and enthusiasts:

Yes, I realize that I'm late.  It's actually 8:15am Sunday
morning here at Fractal Central, and I'm just now getting around
to writing and posting the FOTD for today.  My excuse is that I
was busy all day yesterday and last evening painting walls in
the new soon-to-be Fractal Central.

Another peculiarity is that I have attached two different
versions of the parameter file of today's FOTD.  Version-1
refers to a separate arches.map file for the color information;
version-2 has the color information included in the normal
manner.  I have attached the .map file required by version-1 to
the bottom of this letter.

Running version-2 of the parameter file can be done in the
normal manner, but the colors will be significantly incorrect
(at least on my monitor).  Version-1 of the parameter file will
give more accurate colors, but before this can be done, the
arches.map file must be edited from the bottom of this letter
and saved in your Fractint directory as a text file named
< arches.map >.

The image itself was created by number 12 in my series of 12
MandNewt formulae, all of which are distortions of the Ikenaga
function.  I named the picture "Mandelbrot Arches" when I
noticed the group of arch-like features spanning the screen
before a multi-colored-sky background.  I considered all aspects
of the image before rating it an above-average 7.

It is this exceptionally smooth background that causes the
inaccuracy when the colors are recorded in the normal manner.
The background should have virtually no visible bands, but this
happens only when version-1 of the parameter file is run.
Running version-2 causes unintended bands to appear.  The
difference is small, but it is there.  This is not a bug in the
program; it is simply an unavoidable result of squeezing the
color information into the very compact 'parameter file' format.

Both versions of the parameter file run in just under 13 minutes
on a 200-mhz Pentium, though it will take a few minutes longer
to get set up to run the more accurate version-1.

Time can be saved by giving Paul and Scott a chance to run the
image and post it to their web sites at:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

and:

          <http://home.swbell.net/sdboyd56/fotd/>

though I can't say which version they'll run and post.

The fractal weather today was sunny but quite cold and blustery,
with an afternoon temperature near freezing, which kept the cats
safely indoors.  They seemed to accept their confinement
unusually well, probably because I gave them an extra treat of
tuna.

Well, I see that it's now time to get started on another day of
work at the up-and-coming new Fractal Central.  It will take
several weeks to finish the new place, so don't worry if the
FOTD is occasionally late in the next month or so.  All FOTD's
will eventually appear.

And I'm about to disappear.  Until next time, take care, and see
you in about 16 hours.

One has a spiral with no filaments, the other has a spiral with one

Are there any areas in the mandelbrot set which have *two* or more
filaments?

Subject: (fractint) C-FOTD  19-02-01  (Zebra Mandelbrot [3])

Classic FOTD -- February 19, 2001 (Rating 3)

Fractal visionaries and enthusiasts:

I was quite busy today, trying to get the new Fractal Central
closer to usability.  As a result, I found almost no time for
fractals.  With no time to try again, I settled on today's
image, which is the first and only scene I investigated.

I named the image, which rates only a below-average 3, "Zebra
Mandelbrot" after the zebra stripe effect around the edges.
Unfortunately, the center is a mass of unresolved chaos.  Other
coloring options likely would have worked better, but I had no
time to try them.

The parameter file renders in 15 minutes on a 200mhz Pentium.  I
leave it to the viewer to decide whether the below-average
result would be worth the effort of running the parameter file.

For those who decide that the result is not worth the effort,
the GIF image file will soon be posted on the WWWeb to:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

and to:

          <http://home.swbell.net/sdboyd56/fotd/>

The fractal weather today was colder but sunny and less windy,
which made it feel a bit more comfortable.  The fractal cats
disapproved of the freezing temperatures, and showed their
disapproval by sitting with their backs to me, actively ignoring
me during the short time I spent with them.

And now, I'm tired.  It's time to shut down the old fractal
shoppe and call it a night.  I'll return tomorrow.  Until then,
take care, and be at peace.

Nope.

OTOH, go deep enough into the second spiral and you can find convincing
"fakes" with two main spiral arms and two filaments, alternating -- zoom
deep enough into these, though, and they turn out to be two spirals each
with one arm and one filament wrapped around each other, then joining and
separating.

Actually, I quite like this one. You should probably have rated it a six and
called it "Tyger Tyger burning bright" ... or maybe "Eye of the tiger"...

Classic FOTD -- February 20, 2001 (Rating 7)

Fractal visionaries and enthusiasts:

The hectic activity at the new Fractal Central continued today,
leaving just enough time for a hurried fractal.  For today's
hurried FOTD it's back to basics, since exploring the basics is
the fastest way of finding a worthwhile fractal.  And what could
be more basic than the classic Mandelbrot set.

A day or so ago Rupert Millard posted two parameter files to the
Fractint list, accompanied by a letter asking whether Mandelbrot
spirals with more than one filament exist.  I'm not sure of the
answer to his question, though I suspect that there are no
spirals with more than one filament.

But even though I could not answer the question, I did a bit of
exploring in one of Rupert's fractals -- the one with the single
filament.  Quite deep in the filament, I found today's image,
which I rated at a 7.

It's a pleasant image, featuring the ubiquitous midget at the
center, surrounded by 16 elephants flanked in turn by oversized
elephant-trunk spirals.  The scene is located in the east valley
area of the large midget on the negative tail of the M-set.

We're exploring in the basics, so I gave today's image the most
basic name possible.  After a tiny bit of thought, I named it
"Mandelbrot Fractal".  Since the image is deep enough to trigger
arbitrary precision math, it is a slow one, requiring almost 3/4
of an hour to render on a Pentium 200mhz from the parameter file.

Considering the slowness of the parameter file, I recommend
giving Paul and Scott a chance to render the parameter file and
post the image to their web sites at:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

and:

          <http://home.swbell.net/sdboyd56/fotd/>

The fractal weather today was much improved, as warm sun and a
temperature of 50F (10C) lured the fractal cats into the yard,
where they romped for over an hour.

Well, I guess that's it for today.  It's already past midnight
here at Fractal Central -- time to shut the old place down.
Until next time, take care, and see you soon.

Subject: (fractint) C-FOTD  21-02-01  (Will-o-the-Wisp [8])

Classic FOTD -- February 21, 2000 (Rating 8)

Fractal visionaries and enthusiasts:

After a day of scraping the remains of worn-out carpet padding
from the floor of the soon-to-be new Fractal Central, I took a
break to wander through the land of fractals.  My path led me to
my MandNewt series and stopped at number 11 of that series.  The
fractint evolver took it from there, producing several likely
candidates for today's FOTD.  I chose the thumbnail that seemed
most promising.

The full sized version of the one I chose may not be the best
FOTD of all time, but it certainly is one of the most
spectacular.  It leaves me a bit humble, since my computer found
the image instead of myself.  I created the color palette
however, and this makes the image at least half mine.

I named the image "Will-o-the-Wisp" when I was reminded of those
elusive ghostly lights sometimes seen in marshy areas at night.
The actual lights are created by the slow combustion of gases
released by the decay of rotting vegetation.  Today's fractal
was created by something almost as mysterious -- the Ikenaga
function -- a function apparently disowned by its creator.

Eleven minutes are required to render the image from the
parameter file on a Pentium 200mhz.  On one of the new PentiumIV
machines, it should render in only a minute or two.  And thanks
to Johnathan, my parameter files now record the color
information without compression error.

Those who would rather download the GIF image than run a
parameter file may find the image posted to the following two
sites:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

          <http://home.swbell.net/sdboyd56/fotd/>

The fractal weather today presented a taste of spring.
Considerable sun and a temperature of 66F (19C) let the cats
enjoy a long comfortable afternoon in the yard, the only problem
being when Tippy chased after a squirrel.  The squirrel escaped
up a tree, from where it scolded Tippy loudly.

I see that it's now time to shut down the fractal shoppe and
call it a night.  Until next time, take care, and for every
fractal that promises much but delivers little, there's a
fractal that promises little but delivers much.

Even when I don't get time to view your fractals, I enjoy your comments
and musings.
I think its cool that we'll all share at the same time that 12hr
day/night in about a months time. It only happens twice a year in spring
and autumn (fall). Gives the equinoxes something that the solstices
don't have, special as they are.

Another stunner Jim.

High point of the day here up the mountain in Portugal is the FOTD.

Most nights I boogie round the image trying different areas and=20
other colour schemes.  Tonight was special.

Will-o-the-wisp is caused by phosgene gas which self-ignites as it =
bubbles up.
Here is the critter that generates it!  A zoom out on the FOTD and a =
touch
of Gallet magic and there it is.

Subject: (fractint) C-FOTD  22-02-01  (The Shells of Time [6])

Classic FOTD -- February 22, 2001 (Rating 6)

Fractal visionaries and enthusiasts:

It was another busy day here at Fractal Central, both with work
and with the task of getting the new Fractal Central ready for
occupancy.  Between rushes however I managed to find time for a
brief fractal search.

I named the fractal image "The Shells of Time" for poetic reasons
and also because some of the features remind me of sea shells.
The rating of an above-average 6 indicates that though the image
is above average, it is not nearly as excellent as yesterday's
8-rated effort.

The formula that led the way features a combination of a little
Z^(-30) with 100 times as much Z^(-0.3).  Yes, I tapped out the
parameters at random, as I do with most of my FOTD's.  A good
feature of the MandelbrotMix4 formula is that nearly every random
combination of parameters produces a fractal with something of
interest.  Even the inevitable blank blue or black screens can
be changed into something by a simple adjustment of the real(p3)
parameter.

With a render time of almost 3/4 hour, the parameter file tries
one's patience.  Since I am temporarily not posting to ABPF, the
way to avoid impatience is to give Paul and Scott a chance to
render the image, and then download it from Paul's site at:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

or from Scott's site at:

          <http://home.swbell.net/sdboyd56/fotd/>

The fractal weather today was sunny and mild, with a temperature
of 54F (12C), but the brisk winds spooked the cats, and chased
them indoors after only a brief romp in the yard.  Since much
colder weather and a heavy snowfall is forecast for tomorrow,
they might not get outdoors for several days.

That's it for this evening, fractal fans.  It's time to shutter
up the old fractal shoppe and call it a night.  But I'll return
in 22 hours with another fractal, the appearance of which is as
much a mystery to me at this time as it is to you.  Until then,
take care, and beware of fractal uncertainty.

Many thanks.

Here in Fractal Central we're at the same latitude as Portugal, but
spring has most certainly *not* arrived.  In fact the weather people
are forecasting 15cm of snow this afternoon.  The cats dislike
snow, so they'll be unhappy.

FOTD in 15 hours.

Subject: (fractint) Fwd: Doug Harrington's "Invitation"

Many of you already know that through a discussion between Paul N. Lee and
Bryan A. Smith, on the eGroup Fractal-World
http://www.egroups.com/group/fractal-world/, a suggestion was made by Paul was
to create a screen saver to allow fractal art to be put in front of the public
to help promote fractal art and allow it to become more prominent. With that
in mind Doug Harrington, <[e-mail]>, suggested that he could
create and promote a free screen saver due to his past experience, and
success, with his own screen saver and what is required for successful
distribution through ZDnet(ZiffDavis).
I know that Paul N. Lee has forwarded some of these messages to the
Fractal-Art mailing list as well as the binary fractal news groups, but I
haven't seen it here. Doug Harrington wants to reach everyone and wanted to
cover as many groups as possible. My apologies for any duplication, to anyone
that has received this information previously.
This project is all inclusive, regardless of your skill level or experience.
You don't have to have a website, but if you do the URL will be included. If
you know of folks who don't post anything anymore, but were once active and
would like to an image included, then please contact them. It would be nice to
have images from some of the "pioneers" from years past.
Doug Harrington is posting updates to the Fractal-World list, Paul N. Lee is
posting updates as well. I can also post any update here, if necessary. Any
questions and/or submissions should go to Doug Harrington,
<[e-mail]>.

Here is what Doug Harrington has written:
Hello,
I will be putting together a screensaver project that will have fractal images
from participating artists. This will be a free screensaver available to all,
that will profile the various fractal artists working in this medium. This is
open to experienced and new artists both! This is a chance to showcase your
art as well as promote your website if applicable. Each image will have the
artists name and also website connectivity.

I would like to extend an invitation and encourage each of you to participate
in this project, to showcase the wide diversity of styles in this art form. If
you are interested please let me know and I will get the details to you. Best
regards, Doug Harrington

ALSO A FOLLOW-UP......................
- -----
 Image file size:
When sending in your image please try to limit it between 100-200kbs (or
reasonably close to that).Otherwise we will wind up with one MEGA final
file size! ;-) This will discourage some from downloading and
experiencing our art.
The image needs to be 800(width) X 600(height) pixel dimension,jpeg
preferably but I can convert bmp etc. if necessary
Also try to compress the image (file size)as much as possible without
compromising quality. Preferably between 100-200kbs max(or close to it).
This is to keep the overall screensaver size down and to encourage
downloads of this saver.

 Signature files:
  Please only add your signature to your art(and date if you wish).  No
website urls etc.  I will add this in as a caption.  I will also include
a copyright notice that all images are copyrighted to each artist.

  Let me know if you have a title for the image and also the website
link you wish to use.

  I plan on including a caption over each image with the artist
name,title (and website link if applicable).  This caption feature will
be as non-intrusive as I can make it and may also be turned off within
the screensaver settings.  It will give users the opportunity to see who
created each fractal image and connect to their website however

The main reason for this is to obtain a good rating from the software
sites editors and they frown on anything that is obviously being used as
just a promotional tool. They look at it from the standpoint of the end
user. This will help get increased final exposure and hopefully a
prominent spot in their listings.

 I believe that we can obtain a high rating for this and have had
success on this with my own. On my own screensavers I use a 7 point font
in a darker color that can barely be seen. This effectively "watermarks"
it and yet is barely noticeable. I have seen screensavers specifically
downgraded because of intrusive info on the images.

That is why the captions are advantageous. The editors know that they
can convey the info the artist wishes but can also be toggled off if the
end user wishes.

 I'm approaching this from the standpoint of first,promoting the art in
general and only secondly promoting our own art and/or sites.

 I hope to have all images submitted by artists interested, within the
next couple of weeks but want to remain flexible in this regard. I will
keep everyone posted periodically as to progress. Doug
