; FOTD -- March 02, 2010 (Rating 8)
; 
; Fractal visionaries and enthusiasts:
; 
; As I said in yesterday's discussion, the strange rectangles 
; exist in the East Valley area of the large split-apart minibrot 
; on the negative X-axis of the Mandelbrot set of the formula 
; Z^(2.003)+C.  And to prove my point, today's image shows a 
; minibrot surrounded by a whole flock of rectangles.  I have 
; highlighted the rectangles by rendering the image with the 
; inside set to brilliant white.
; 
; I rather enjoy the overall pattern surrounding the minibrot, 
; which would be worth a FOTD even without the rectangles.   With 
; the rectangles included, the image rates an 8.  The name "Mandel 
; Rectangles" explains itself.
; 
; The calculation time of 1-1/2 minutes will pass like greased 
; lightning.  A trip to the FOTD web site at:
; 
;        <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
; 
; where the finished image is posted for instant happiness, will 
; pass even faster.  But note that in a few days the address of 
; the web site will change.  I will post the new internet address 
; in tomorrow's FOTD.
; 
; The partly cloudy skies and temperature of 45F +7C here at 
; Fractal Central on Monday kept the fractal cats leaping on and 
; off their window shelf.  They finally gave up trying to catch 
; the sun and settled for an extra treat of tuna.  My day was 
; rather busy.  The next FOTD will be posted in 24 hours.  Until 
; then, take care, and walk with your heads held high.
