[Fractint] FOTD 27-11-10 (The Great Fan [7])

27 Nov 2010

      FOTD -- November 27, 2010 (Rating 7)

Fractal visionaries and enthusiasts:

In many fractals of today's double-negative type, I tell of a 
prominent 'fan' in the parent fractal.  Until now however, I 
have been pretty much ignoring this 'fan'.  In today's image 
this oversight has been corrected.

The image shows one of these 'fans' in its full glory.  The 
handle of the fan is at the origin of the fractal, while the 
blade points directly east.  Today's image has been rotated 90 
degrees, so that the blade points straight up instead of to the 
right.

Minibrots abound in these fans, especially along the edges, 
though sometimes they are difficult to find.  Quite a few mini-
brots are buried in today's image, and I just might find a few 
of them and turn them into the FOTD's of the next few days.

The name "The Great Fan" says it all.  The rating of a 7 makes 
the task of running the parameter file a minor one, especially 
since the image finishes in a lightning-fast 23 seconds.

The finished image is or soon will be available on the FOTD web 
site at:

Morning clouds cleared away for afternoon sun here at Fractal 
Central on Friday.  The temperature of 39F +4C and brisk winds 
kept things chilly, but were nothing that would be considered 
exceptional in late November.  The fractal cats kept snug on 
their shelf in the strong afternoon sun.

With the work caught up and the holiday past, my day was relax-
ing.  The next FOTD will be posted in 24 hours.  Until then, 
take care, and when the truth shines through the fog, will it be 
recognized even if it proves to be irrational, or is irrational 
truth an absurdity?
