Fractal visionaries and enthusiasts:

Due to a not-totally-unexpected antiquing trip out to Big Valley, today's image is a quickie that I found in a hurry when FL and I got back from the day's adventures.

The parent fractal is a complex thing with several large vertically stacked bays that resulted when I combined 5 negative parts of Z^(-1.5) with 1.5 negative parts of Z^(-4.5) and added (1/C) on each iteration.  The southernmost bay is the largest, and is also the most obviously critical one.  Today's scene lies in the debris on the northeastern shore line of this largest bay.

I named the image "On the Half-Shell".  Something in it must have reminded me of oysters, though whatever it was has been totally forgotten.

The rating of a 7 is a come-down from the sky-high ratings of recent images, but it's still above average as far as fractals go.  (At least IMO)

The calculation time of under 1-1/2 minutes will pass in half a flash, and then you will see if the image was worth the effort.

The sky was mostly sunny today here at Fractal Central, but the temperature of 37F +3C was a bit brisk for leisurely outdoor activity.  The fractal cats made the most of things by staying close to the heat while FL and I were away.

The next FOTD will be posted in the near future, whenever that turns out to be.  Until next time, take care, and if someone commits a crime because of a quirk in their brain chemistry, as neuro-biologists tell us sometimes happens, punish the guilty chemicals, not the innocent perpetrator.
