FOTD 07-12-11 (Starfish Playground [9.5])

8 Dec 2011

      FOTD -- December 07, 2011 (Rating 9.5)

Fractal visionaries and enthusiasts:

Today's image lies in the same parent fractal as yesterday's, 
but instead of lying in East Valley, today's image lies near the 
terminal point of the filament extending from the large bud on 
the south shore of the main bud of the parent, which is shaped 
like the body of a stringed instrument.

When I first saw the image, I had to double check to be sure I 
had not inadvertently reset the 'outside' to something other 
than the standard 'iter'.  When I did, I found that the dagger-
like features are real, and not mere artifacts of a fancy 
algorithm.  (IMO, the equal-iteration-band method creates the 
only 'true' fractals.)

The image, with its vaguely threatening streaks of brilliant 
colors, rates an honest 9.5, which is really outstanding by FOTD 
standards.

I named the image "Starfish Playground" when something in the 
scene reminded me of an 8-armed starfish.

The calculation time of 2-1/4 minutes is quite a bargain for 
such an unusual image.

And even this brief time may be saved by viewing the image 
already calculated and posted to the official FOTD web site at:

The heavy clouds continued today here at Fractal Central, as did 
the rain, and to make matters worse, the temperature dropped to 
a raw 43F +6C, with a forecast of snow tonight.  The fractal 
cats, who never venture outside, felt sorry for the humans, who 
do venture out.

The next FOTD will be posted in 24 hours, but there is no 
guarantee that it will be another image rating a 9-1/2.  Until 
then, take care, and I just won the Microsoft Lottery for the 
ninth time, but I have yet to see a single U.S. dollar.
