Fractal visionaries and enthusiasts: 

Today's image lies in the parent fractal that results when 3.5 parts of Z^(-1.1) are combined with 0.5 part of Z^(-5.5) before (1/C) is added on each iteration.  The default screen view of this parent is little more than a field of unorganized blobs forming a hint of a valley, but two full outzooms reveals a fully formed but quite distorted Mandeloid, with a ring-lined filament extending southeast to where it joins a large ring.  Today's scene, with its abundance of sharp bright spikes, lies near the point where this filament joins the large ring.

Since the season is one of fright, and sharp things such as daggers and axes are trendy at this time of year, when I saw the scary sharpness in the image, I named it "Fright Night".

With a modicum of coloring effort going into the image, its rating is worth an honorable 8.  The math worth remains a 6, since the MandAutoCritInZ formula has been doing its thing for over a decade, and has long since lost its math impact.

The calculation time of 4 minutes is slow, no denying it, but once again the web sites are on the job, with not only the original image but assorted variations as well.

Today brought a mix of sun and clouds to Fractal Central, while the breeze from the northwest and temperature of 54F 12C added a proper end-of-October atmosphere to the scene.  The fractal cats, still interested in getting accustomed to each other, had little interest in the outside conditions.  The humans had a reasonably quiet day.

The next FOTD will likely be posted in about one day, but possibly two days.  Until next time, take care, and they can't put it on the news shows if it isn't true.  Or can they?...
