; FOTD -- January 31, 2013 (Rating 7)
; 
; Fractal visionaries and enthusiasts:
; 
; Today's image will be the last until at least February 4.  We're 
; doing a bit of remodeling here at FC.
; 
; The image rates a 7.  I'm not sure why I gave it such a rating.  
; Perhaps it is the most disorganized of all time.  I can spot at 
; least a dozen themes in the scene, all trying to predominate but 
; none winning.  The arc of quadrilaterals, which inspired the 
; name, is probably the most obvious, though several others are 
; giving notable competition.
; 
; The parent fractal came about when I combined 10 negative parts 
; of Z^(-1.2) with 0.1 negative part of Z^(-12.2) and added (1/C) 
; on each iteration.  It consists of two well-separated parts.  
; The main part, which lies at the center, holds a superb fractal 
; 'fan'.  The second part lies well northeast of the main part and 
; consists of a series of rings with a well-defined minibrot 
; within these rings.  Today's scene lies at the northeast edge of 
; the superb 'fan'.
; 
; The calculation time of 3-1/2 minutes borders on slowness.  And 
; unfortunately, the image will not be posted on the official web 
; site for several days.  It will be available sooner however at:
; 
; <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html>
; 
; The library of FOTD back images is at:
; 
;        <http://www.Nahee.com/FOTD/>
; 
; Today brought a mix of sun and clouds with occasional heavy 
; showers of snow to Fractal Central.  Luckily, the above freezing 
; temperature of 34F +1C melted the snow about as fast as it fell. 
; The fractal cat spent most of the afternoon in his watch window, 
; chasing the sun and wondering what all the snow was about.  The 
; humans passed the day finishing the commercial work.
; 
; The next FOTD will not be posted before February 4, and maybe 
; not until a day or two later.  Until whenever, take care, and as 
; the millionaire who had just gone bankrupt said, "put the past 
; behind you and look ahead to the future."
