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.
