Fractal
visionaries
and enthusiasts:
Today's unlikely scene came about when I mixed various parts of (1/Z),
(Z), (Z^2) and Z^(-0.5) to produce a parent fractal almost beyond
description. This quirky mixture has critical points at
0.225...
and -0.262... Today's parent is the one that is created when
Z is
initialized to -0.262...
The closest I can come to describing this parent is to say it vaguely
resembles half a Mandelbrot set split right across the middle and
giving birth to a shapeless blob. Today's scene is located in
a
valley on the west side of the blob.
This parent fractal is indeed critical. This is confirmed by
the
intact M-set shaped minibrots that fill it. But today's image
shows open holes of a different sort. These midgets, if they
are
minibrots at all, are shaped nothing like baby M-sets, they resemble
something closer to stone-age arrowheads. And as a few
zoom-ins
will show, they fill the scene.
I named the image "Flying Flinders", though I have no idea what might
have just exploded and filled the air with the flinders.
The artistic value of the image rates a humble 5. What more
could
I do for an image with so little going for it. I rated the
math
aspect at a question mark because the formula has nothing really new in
it.
But today's arrowhead minibrots are not all the parent has in
it.
With so many widely varied areas, who knows what might turn
up.
I'll give the parent a couple more good examinations before trashing it.
The calculation time of 3-3/4 minutes is slow because the scene lies
rather deep in a valley, and also because the formula is a slow
one. Time may be saved by checking the finished image on one
of
the FOTD web sites.
After a foggy start, the afternoon turned perfect here at Fractal
Central today, with photoshop blue skies, decorative cirrus clouds and
a temperature of 72F 22C, which was right on the mark. The
fractal cat was more interested in the increasing number of pigeons
than in the weather. The humans took several glances at the
weather, then turned to more human things. The next FOTD will
be
posted whenever it is. Until that magic moment arrives, and
it
could be as near as 24 hours, take care, and see you in the fractal
shop soon.
