[Fractint] FOTD 14-10-14 (In a Petri Dish [A-8,M-5])

14 Oct 2014

      FOTD -- October 14, 2014 (Rating A-8,M-5)

Fractal visionaries and enthusiasts:

Today's image is named "In a Petri Dish".  I gave it this name 
in recognition of the current germ scare filling the TV news 
channels.  The image, with its sickly brown and greenish colors, 
does remind me somewhat of a disgusting culture growing in a 
petri dish in some secret biological laboratory.

But actually, it's nothing more than a scene in the parent 
fractal that results when 0.72 part of Z^(1.4) is combined with 
0.72 part of Z^(-1.4) and (1/C) is added on each iteration.  
This parent consists of a large figure-8-shaped bay, with a 
symmetrical ring of debris filling both branches.  Today's image 
lies in the debris making up the southern part of this ring.

The image itself is rather striking, which justifies the 
artistic rating of an 8.  The math is old hat however, and could 
be rated no higher than a 5.

The calculation time of 2-1/2 minutes is about FOTD average, 
neither surprisingly fast nor disappointingly slow.  And as 
always, the web sites will make the viewing simpler.

Lots of clouds and occasional bursts of sun made today's weather 
undecidable here at Fractal Ccentral.  The unusually mild 
temperature of 75F 24C was pleasant enough, but the brisk breeze 
occasionally became annoying.  The fractal cats, happy despite 
the weather, slept and played most of the day, while the humans 
tended to human things.

The next FOTD, hopefully germ free, will be posted in a 
reasonable time.  Until reason prevails, take care, and stay germ 
free.
