November 20, 2011: Peanuts in the Knight | Nov. 19 | Nov. 21 | 2011 | FOTD Home |
Fractal
visionaries
and enthusiasts:
Perhaps the most striking feature of today's image is the name I gave
it. "Peanuts in the Knight" is the first phrase that came to
mind
when I shut off rational thought in search of an interesting
name. Since the name found me rather than me finding it, I
have
no logical connection between the name and the image other than the
vaguely peanut-shaped holes surrounding the minibrot. And
nothing
that I can see in the image even hints at a noble knight of long
ago. I also doubt that peanuts were on a knight's list.
The parent fractal of today's image came about when I subtracted two
parts of Z^(1.5) from Z^(2) on every iteration before adding
(C).
This parent fractal, which lies totally in positive real territory, is
a Mandelbrot set with a reasonably normal main bay east of Seahorse
Valley, but when we pass west of Seahorse Valley, where the circular
period-2 main bud would be expected, we find a surprising north-south
series of three partially merged buds. Today's image lies
near
the X-axis on the western edge of this series of buds.
The rating of a 6 is all I could do for the image. I could
have
spent more time on the coloring, but I saw too little potential to make
the effort.
The calculation time of 1-1/3 minutes is near average for a FOTD image.
A mix of sun and clouds prevailed here at Fractal Central
today.
The fractal cats enjoyed the sun more than the clouds, and had no
comment on the temperature of 55F 13C, which was quite mild for
mid-November. My day was reasonable enough to please a
rationalist, yet weird enough to satisfy a believer in aliens in flying
saucers from outer space. FL, being of a far more pragmatic
nature, had a day with a minimum of un-necessary speculation.
The
next FOTD will be posted in 24 hours. Until then, take care,
and
stay sharp when life turns dull.
