Fractal of the Day
by Jim Muth

Fractal visionaries and enthusiasts: Today's C-FOTD is a closer view of the midget at the center of yesterday's "Challenging" image. I named it "Challenge Variation" accordingly. Since too much of a good thing is not always as good as it seems, I rated today's image a 6, a two-point come-down from yesterday's image. In today's image the maxiter has been lowered to 500, a value barely enough to resolve the midget, and the color palette has been changed from a somber violet theme to a joyous celestial blue. The lacework effect in the elements surrounding the midget is an illusion created by the coloring. The 4-1/2 minute render time of the parameter file is far better than the 15-hour wait for the GIF image file to be posted to Usenet at: After a very frosty start, the fractal weather was ideal for cats most of the day, with bright sunshine and a temperature of 45F (7C), which lured the dynamic duo into the yard, where they passed the afternoon investigating whatever they found there to investigate. As for me, I've about had it for the day. It's 9:50pm of Saturday evening, and almost time to toss reason to the winds and watch the junkiest old sci-fi or horror movie I can find in my vast collection of junk. I won't know what it will be until the tape starts playing. Until tomorrow, when some fractosophy is likely to appear, take care, and keep your fractals handy. Jim Muth jamth@mindspring.com |
