April 25, 2013: Butterfly Cookies | April 24 | April 26 | 2013 | FOTD Home |
Fractal visionaries and enthusiasts:
Today's
image is
named "Butterfly Cookies". The obvious reason is that it
reminds
me of butterfly cookies. In fact, it reminds me so much of
the
cookies that, when I saw the image, I ran to the local store to pick up
a box.
The recipe behind the cookies combines a measly 0.1 part of Z^2 with a
full part of Z^(-3) then adds C on each iteration. The
resulting
parent fractal is an oversized thing closely resembling some of those
created by the parallel-resistance formula posted on the list a week or
so ago. Its Mandelbrot shape is apparent, but the normally
empty
inside parts are filled with all kinds of superfluous
decorations. Today's scene lies on the X-axis just beyond a
large
minibrot on the skeletal negative spike.
The rating of a 7 is an improvement over yesterday's, but still leaves
lots of room for improvement. Hopefully, tomorrow's image
will
rate an 8, but there is no guarantee that it will not check in at a
rating of an embarrassing 6.
One thing not in dispute is the speed of today's image. On my
far
from SOTA machine it finishes in 20 seconds. Some of the
current
units will finish it in far less time, that is if they can run the old
Fractint DOS program at all. Regardless, the image is
available
on the FOTD web sites.
The weather was near perfect here at Fractal Central today, with
photoshop (old-kodachrome) blue skies and white cotton-puff cumulus
clouds. The only thing not perfect was the temperature, which
at
a high of 57F 14C was notably chilly for late April. The
fractal
cat would have preferred more sun on his shelf. But now that
the
sun is at a much higher angle it strikes only the edge of the shelf
closest to the window. The humans, not very concerned with
sun
angles, had an average day.
The next FOTD will be posted in a number of hours. Until that
mysterious number of hours passes, take care, and thanks to science we
have life better today than at any time in the past. Why then
are
so many people dis-satisfied with their lives?

A WOMAN'S RESPONSE TO YESTERDAY'S POST: Female hormones sometimes cause women to fall for handsome, screwed-up men. Male hormones sometimes cause men to commit acts of senseless carnage. Which gender should we REALLY be worried about?
Dzhokhar Tsarnaev has a haunting face which seems specially designed to touch female hearts. My heart has led me to try to learn more about him. It seems plain that in his confused mind (as in the minds of other terrorists) he really believes he is a soldier defending his Islamic brothers and sisters. To me, he is as tragic as his victims.
