[Fractint] FOTD 23-11-10 (Minibrot in Bloom [8])

23 Nov 2010

      FOTD -- November 23, 2010 (Rating 8)

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

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 work-
out 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.
