FOTD 17-02-10 (The Big Wheel [No Rating])

17 Feb 2010

      FOTD -- February 17, 2010 (No Rating)

Fractal visionaries and enthusiasts:

Laziness took a setback Tuesday when a new job came in, but a 
fractal still appeared, almost by magic.  The fractal is another 
of the near-Julia Seahorse Valley kind -- this one of order 15.

Most of the effect was achieved by rendering the scene with the 
outside set to 'tdis', and also by the coloring.  With nothing 
new in the image, I could not give it a rating.  The name "The 
Big Wheel" refers to the circular arrangement of fifteen smaller 
buds around the circumference of the large bay.

The calculation time of 2-1/3 minutes is surprisingly fast; the 
trip to see the finished image on the FOTD web site at:

       <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

will be even faster.  But before surfing, give Paul a chance to 
post the image.

Light snow continued Monday night here at Fractal Central.  By 
the time it ended at 10am Tuesday about 1-inch 3cm had piled up. 
Tuesday afternoon turned mostly sunny, while the temperature 
hovered around freezing and the fractal cats took things easy.

The next FOTD will be posted in 24 hours.  If all goes well, it 
will be something new.  Until then, take care, and if a fractal 
isn't broke, don't try to fix it.
