Fractal
visionaries
and enthusiasts:
Today's image is an 'evaporated ' one created by the good old
MandelbrotMix4 formula, the most prolific producer of FOTD images in my
collection.
To achieve the image, a bit of Z^(-11.1) was combined with Z^(-1.1),
and (1/C) was added. Then the entire thing was 'evaporated' by
raising the escape radius to an astronomical one-googol, which means
that every point on the Cartesian plane is trapped, leaving the screen
a flat color.
But luckily, the Fractint program can do things with such hopeless
images. It has certain inside fills that check the things the
points do even though they are trapped. In today's case, the
'bof61' inside fill reveals the ghost of a midget that was located at
that point before the image was evaporated.
Since I am reasonably unimpressed with the result, I gave the image
neither name nor rating.
A few months ago, Paul Lee, who runs the FOTD web site, made an offer
to expand the site. At the time I declined the offer, but I think
I will soon reconsider. Stay tuned for possible changes soon to
come.
The unseasonably chilly weather continued Monday here at Old Fractal
Central, making things rather unpleasant for the fractal cats, who
desire warm breezes and lots of tuna. Unfortunately, the tuna was
all they had on Monday. In my department, the work turned heavy,
though still under control. The next FOTD is due to appear in 24
hours. It actually might do just that. Until then, take
care, and be of good faith.
