; FOTD -- May 24, 2010 (Rating 6.5)
; 
; Fractal visionaries and enthusiasts:
; 
; For some strange reason, today's image reminds me of two ships 
; passing peacefully in the night, which explains the name 
; "Passing in the Night".  But the image does not show two ships 
; passing; it shows two almost-Julia sets arranged in a symmetri-
; cal pattern around an imaginary point.
; 
; The image is located in the Seahorse Valley complex of the large 
; minibrot on the main spike of the Mandelbrot set.  The orienta-
; tion is double-rotated 0.005,0.005 degrees from the true Julia 
; direction.  As is true of many near-Julia sets, this tiny rota-
; tion makes a world of difference in the appearance of the inside 
; parts of the parent fractal.
; 
; The twin almost-Julia-set theme of today's image is repeated 
; without change at ever smaller scales at the centers of the 
; Julia sets in the image, apparently all the way to infinity, 
; which is the way things usually go in the world of fractals. 
; 
; The basic image rates a 6.  The extra half-point that brings the 
; rating to 6.5 is a reward for the effort I put into coloring the 
; scene in an effort to make the almost-Julia sets resemble real 
; three-dimensional objects.
; 
; The calculation time of 5 minutes is true on the 2000mhz unit.  
; Surprisingly, on the 200mhz unit the same image finishes in well 
; under 9 minutes, which is only 1.8 times the running time of the 
; supposedly 10 times faster unit.  Even more surprising, with 
; type=mandel fractals the 10-times-faster machine runs almost 20 
; times as fast.
; 
; But why not forget this timing confusion by visiting the FOTD 
; web site at:
; 
;        <http://www.Nahee.com/FOTD/>
; 
; and viewing the finishedimage there.
; 
; Clouds and occasional light showers of rain marred Sunday here 
; at Fractal Central, though the temperature of 75F 24C could 
; hardly have been improved upon.  The fractal cats showed their 
; dis-satisfaction when they got into a spat to decide who would 
; spend the afternoon on the ottoman foot-stool.  Cassie won the 
; minor dispute with a loud hiss and a hit to Nicholas' head.  
; Nicholas then sulked for an hour or so.
; 
; My day was about average; most likely Monday will be the same.  
; The next FOTD will be posted in 24 hours.  Until then, take 
; care, and everything that happens above the quantum level has a 
; probable cause, but does it have a reason?
