Fractal of the Day

Fractal visionaries and enthusiasts: I hope I've got everything right tonight. Last night, when I tried to post my FOTD, I found both Mindspring (Earthlink) and AOL inaccessible. Finally, early this morning, when I gained access, I forgot to update the image name. But no harm done -- the image wasn't that good anyway. Today's image is better, at least good enough to rate a somewhat above average 6. The brilliant object in the picture reminds me of a meteor plunging through earth's atmosphere on its way to a surface impact, which is why I named the image "Meteor Impact". The actual meteor is a midget in a remote part of the Z^1.195+C fractal. And I did touch up the colors in a graphic program. When I run the image through a graphic program, I never change it so much that it cannot be defined in a parameter file, so running the parameter file will produce exactly the same image as has been posted to: The fractal weather was perfectly perfect all day, with a temperature of 62F (16.5C) and not a single cloud to mar the deep blue sky. The fractal cats showed approval by lounging in the yard for several hours, trying to decide what trouble to get into. My philosophical muse has been absent ever since I lost that long FOTD article a few nights ago. I'm hoping she'll return before too long. Until tomorrow, take care, and be good, but not too good.
