; FOTD -- October 13, 2011 (Rating 8)
; 
; Fractal visionaries and enthusiasts:
; 
; Believe it or not, today's image is a scene in the Seahorse 
; Valley area of the (-Z)^(1.5)+C Mandeloid.  Actually, the scene 
; is very close to a Julia set of the valley, being double-rotated 
; only 0.4,0.4 degrees from the true Julia direction.  The wedge-
; shaped feature almost filling the outer figure-8 shape is a 
; grossly enlarged view of the Mandelbrot Seahorse Valley.
; 
; Iterating (-Z) rather than straight (Z) makes a great difference 
; in the fractals with a fractional exponent of Z between 1 and 2. 
; While positive (Z) results in tiny bean-shaped fractals, 
; negative(Z) produces much larger fractals, with recognizable 
; Seahorse Valleys and much more interesting surrounding semi-
; chaos to explore.
; 
; I rendered the scene with the outside set to 'tdis'.  Some of 
; the other outside options also produce interesting versions of 
; the scene.
; 
; The name "1-1/2 Seahorses" refers to the exponent of Z, not to 
; any sliced up seahorses that might be lying around.
; 
; The rating of an 8 includes a full point for the coloring.  This 
; might be a bit excessive, but why not reward myself?  I must 
; have put almost an hour into working out the colors.
; 
; The calculation time of 8-3/4 minutes is on the slow side.  Most 
; of this time is caused by the large maxiter of 32767, which was 
; the maxiter limit of early versions of Fractint, and which I 
; still use as a standard setting.
; 
; But wait!  There is no need for the 8-minute delay.  Calculation 
; may be avoided by viewing the image already calculated on the 
; official FOTD web site at:
; 
;       <http://www.crosscanpuzzles.com/Archives.html>
; 
; And by viewing the high-definition version at:

; 
; Heavy clouds and intermittent showers continued here at Fractal 
; Central on Thursday, while the temperature of 63F 17C was on 
; the mild side for the season.  The fractal cats, being warm 
; weather fans, enjoyed the conditions.  The humans spent the day 
; doing routine things, which make for a peaceful day to live 
; through but rather dull reporting.  The next FOTD is scheduled 
; to be posted in 24 hours, and it might actually be ready.  Until 
; next time, take care, and if we ever defeated the terrorists, 
; who would we then blame our problems on.
