November 23, 2010: Minibrot in Bloom | Nov. 22 | Nov. 24 | 2010 | FOTD Home |
Fractal
visionaries
and enthusiasts:
I had intended November to be exclusively a month of odd slices of the
Z^2+C Julibrot, and here we are 3/4 of the way through the month, with
quite a few interesting odd-slice scenes to show for the
effort. While searching for an odd Julibrot slice today
however, I came up blank, but the workhorse MandAutoCritInZ formula
rescued me in the nick of time.
The image shows a minibrot in a valley at the southern edge of the
superb fan of the parent fractal, which was created when I combined 11
negative parts of Z^(-1.1) with one negative part of Z^(-11), and added
(1/C).
I rated the image at an 8, including a full point for the extra
coloring effort. I named the image "Minibrot in Bloom" when I
noticed FL raking leaves out in the back-yard garden.
The calculation time of 3-1/4 minutes is well within reason for an
image that rates an 8. Viewing the image already calculated
on the FOTD web site is even more reasonable. The web site
may be accessed at:

Morning clouds gave way to afternoon sun here at Fractal Central on
Monday, while the temperature reached a pleasant 57F 14C. The
fractal cats occupied themselves for an hour or so chasing the laser
beam up and down the hallway. After the workout they were too
exhausted to do much but sleep and ask for
food.
My day was rather slow. In the afternoon I spotted FL raking
leaves in the garden, but she finished before I could go out and
help. The next FOTD will be ready in 24 hours.
Watch for it then in this same spot. Until next time, take care, and
I'll tell you how if you tell me why.
