; FOTD -- July 20, 2005 (Rating 4)
; 
; Fractal visionaries and enthusiasts:
; 
; After yesterday's abysmal effort, I had hoped to have a better 
; fractal for today.  The fractal is better, true enough, but how 
; much praise can I give an image that rates a humble 4?  We will 
; need to do better still in the next FOTD.
; 
; In today's image I set the outside to the 'epsiloncross' option, 
; an option I rarely use.  The result is an image with black arcs 
; that seem to be holding hot magma in place.  I named the image 
; "Iterative Eruption".  It was created by combining various 
; portions of Z^(-2.2) and Z^(-1.2), then adding (1/C).
; 
; The render time of 3-1/2 minutes is within reason, but the 
; 'passes=g' option will cut another minute from that time.  
; Perhaps the fastest way to see the image is to download it 
; already rendered from the FOTD web site at:
; 
;        <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
; 
; A temperature of 93F 34C combined with a hot sun was too much 
; for the fractal cats on Tuesday.  They passed most of the day 
; indoors under the air conditioner, going outside only long 
; enough to convince themselves that the indoors was the better 
; choice.  A tough looking tomcat wandering the area might have 
; helped them decide to stay inside.  Today is starting with sun 
; and clouds, still hot but less humid.  The cats have yet to 
; decide what to do.
; 
; I have no problem deciding what to do.  Having one's work pre-
; arranged is one of the benefits of adulthood.  The next fractal 
; will appear in 24 or so hours.  Until then, take care, and get 
; in there with the big time thinkers.
