October 17, 2012: Spokes and Spirals | Oct. 16 | Oct. 18 | 2012 | FOTD Home |
Fractal visionaries and enthusiasts:
The
parent fractal
of today's image is one of the most unpromising of all time -- little
more than a large open circle with degenerate buds along its
circumference. But the east side of this circle holds hints
of
Mandelbrot stuff, and as one looks closer, the hints prove to be entire
worlds. Today's scene lies in a remote non-critical valley
near
an unpromising bud in this island of chaos.
To create the parent circle, I combined 1/2 part of Z^2 with 1/10 part
of Z^3 on each iteration, then and added 1/C. Perhaps the
most
interesting feature of the image is its combination of open areas,
straight spokes and spirals. The spokes and spirals explain
the
name.
The rating of 7-1/2 includes a half-point bonus for my work on the
colors. It really did take nearly 1/2 hour to get the colors
almost right.
The calculation time of 15 minutes will pass slowly. But here
is
where the FOTD web sites come in handy.
When the morning fog cleared off, sunshine ruled the roost here at
Fractal Central today. A few decorative angel-hair cirrus
clouds
in the afternoon merely added to the splendor. Fractal cat
Nicholas passed the afternoon sleeping in the sun. From the
way
he sometimes behaves since Cassie's departure, I would assume he is
interacting with her conscious left-over energy field. (Could
I
call it her spirit without arousing the wrath of rationalists who know
that conscious spirits do not exist? [I guess it's all right
as
long as I consider such belief to be merely a comforting and harmless
fantasy.])
FL passed the day putting her garden to sleep; I passed the day
pondering the mysteries of existence. The next FOTD will be
posted when the time is right. Until whenever, take care, and
how
can we make statements about the existence of things like spirits when
we can't even agree on whether the Mandelbrot set actually
exists? (I, for one, have seen nothing of the set more than a
lot
of pictures.)
