Fractal visionaries and enthusiasts:

For the first day of the new month, we return to the MandAutoCritInZ formula, a work-horse if ever there was one.  We check the parent fractal that results when 2 negative parts of Z^(-22) are combined with 10 negative parts of Z^(-1.2) and (1/C) is added on each iteration.

This parent fractal is an oversized thing consisting mostly of a large 'fan' with minibrots scattered along the edge of its blade.  Today's scene is located in the East Valley of one of these minibrots.

I named the image "Filigree" because of the delicate lace-like network surrounding the prominent central minibrot.  Most of the lacy effect was created by rendering the image with the 'outside' set to 'summ'.

The rating of an 8 is well above average, though I'm not sure it justifies the 8 slow minutes required to run the included parameter file.

Except for those in heaven, all good things must come to an end.  The end of the sunny, spring-like weather came to Fractal Central today as clouds and rain moved in.  The temperature of 52F 11C was still mild enough, but the mildness was hard to enjoy with the showers falling.

The fractal cats checked the weather from their window shelf, then decided it would be a better day by the heat.  The two local humans made it through another day uneventfully.  The next FOTD will be posted in 24 hours.  Until then, take care, and where would we all be if the big bang had never happened.  (Then again, since no one observed it, maybe it never did happen.)
