November 4, 2012: Two and a Half | Oct. 29 | Nov. 5 | 2012 | FOTD Home |
Fractal visionaries and enthusiasts:
Things
have finally
settled down enough here at FC to once again devote energy to the
FOTD. Today's image is a scene in the parent fractal that
results
when the expression Z^(2.5)+C is iterated 5.2 levels up the hyperladder
with no function applied.
This unimpressive parent resembles a Mandelbrot set rotated so that the
area normally on the west faces northwest, with a large jagged bay
where its East Valley should be and a main bud that has two equally
large sub-buds. Filaments extend from each of these sub-buds,
with large minibrots on these filaments.
Today's scene lies in the large minibrot on the filament extending from
the north sub-bud. This minibrot has two 'main' buds, with a
rudimentary bay between them. This bay is the home of today's
image.
I rated the image at a 7-1/2. If I had had more time, I might
have improved the colors enough to raise the rating to an 8.
As
it is, the image is not all that bad to look at, and well worth the
1-3/4 minutes required to calculate it.
The name "Two and a Half" refers to the exponent of iterated Z.
Today was cloudy with a temperature of 43F +6C. The fractal
cat
is doing fine. His new companion is due on November
14. The
humans are still in the clean-up process.
I have much to say about the big N.E. storm and the things I am hearing
about it, but these things are mostly political, with lack of knowledge
abounding, and this is a fractal list. I'll soon voice my
opinion
on the official FOTD web site, where I will be starting a blog where
anything goes.
The next FOTD will be posted when I get a 'round tuit'. Until
whenever, take care, and instead of continuing to blather about the
Arctic ice, let's talk about what's happening to the much more
plentiful ice in the Antarctic.
