Fractal
visionaries
and enthusiasts:
For some reason, today's image reminded me of a caterpillar, so I named
it "Caterpillar Fractal". The rating of a 6 is just a little
above average.
The image is almost a Julia set of the Z^(1.5)+C Mandeloid. It is
not a true Julia set because I have rotated the slice a small bit from
the true Julia orientation. The rotation is less than one degree,
but to see the difference such a small rotation can make, change the
four p1 and p2 parameters to 90. This will show the true Julia
set.
A fine late winter day on Wednesday here at Old Fractal Central pleased
the aging fractal cats. Partly cloudy skies with a temperature of
50F 10C and little wind made conditions in the yard quite
pleasant. The duo spent over two hours outside, watching for
intruding cats.
Meanwhile, inside FC, the work was heavy but under control. The
next FOTD fractal is expected in 24 hours. And unless something
arises that would prevent it, the fractal actually will appear as
scheduled. Until that awesome moment arrives, take care, and
don't get awe-struck too soon.
