FOTD -- October 30, 2009 (No Rating)
Fractal visionaries and enthusiasts:
Now and then I sneak in a blast from the past, in which I do a
slight reworking of an earlier FOTD image -- today's image is a
reworking of an early image indeed. The first version appeared
over 12 years ago in April of 1997 -- the first month of the
FOTD, at a time when I was interested in what I call 'ghost
buds', vague ghostly high-iteration things that often appear in
the background of the perturbed Mandelbrot sets. (These ghost
buds appear because regardless of where the points start, if
they do not escape first, they eventually settle into the same
orbits as the points that start at 0,0.)
The effect of the monstrous banded elements in the foreground
was created by the 'ranges' feature of Fractint, a little used
feature that, as far as I know, can be accessed only through the
command line.
The scene lies in the perturbed M-set with a starting point of
the square root of 0.777,-0.555. (For some reason, the
type=mandel fractals are calculated with a starting point equal
to the square root of the entered complex number.) The scene is
located on the north shore of the main bay, just west of the
large period-3 bud.
The large ghost bud in the background has a periodicity of 14.
The smaller buds have a much higher periodicity.
The maxiter of 32767 is actually too low to fully resolve the
image, but the 'ranges' option does not work with a maxiter
higher than this.
The name "The Second Time Around" admits that today's image is a
near-repeat of one that appeared over 12 years ago. I could
hardly give a rating to a repeat, so I let the image go unrated.
The calculation time of a fireball 19 seconds will bring no
hardships.
And as always, the finished image is available on the FOTD web
site at:

Heavy clouds that hung on all day made Thursday unpleasant here
at Fractal Central. The temperature of 57F 14C did nothing to
improve things. The fractal cats found comfortable spots and
slept through most of the day.
For me, the day was about average, even though the fractal was
not quite up to FOTD standards. The next Fractal of the Day
will be posted in 24 hours. Until then, take care, and wait for
what you wish for.
