FOTD -- November 07, 2009 (Rating 8)
Fractal visionaries and enthusiasts:
I was going to name today's image "Sandy Claws", but I decided
to name it "A Minibrot in the Sand" instead. The image is a
scene on the main stem of the chaotic Mandeloid that results
when Z^(2) and Z^(-2) are combined in a crazy way.
When a negative exponent of Z is involved in a formula, the
resulting fractal is highly dependent on the bailout radius.
The 3000000 entered as the second parameter acts as somewhat as
a bailout radius. I set this parameter at the point where the
image is on the verge of evaporating, and let it rip. The
result was interesting enough to be FOTD for today.
The rating of an 8 might be a bit optimistic, but I feel the
image is worth it. The calculation time of 2-3/4 minutes is
certainly a bargain.
The most convenient way to view the sandy image however is to
surf out to the FOTD web site at:
<
http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
and be exalted in its radiant glory there.
Total sun but chilly temperatures prevailed here at Fractal
Central on Friday. The fractal cats enjoyed the sun while it
was beaming in the window, then took their places by the hall
radiator.
My day was average, which is just about all I can say about it.
Due to a trip back to Old Fractal Central on Saturday, there
will be no FOTD for November 8. But the FOTD for November 9
will be posted on schedule. Until then, take care, and don't
get caught up in the feel-good craze.
