June 11, 2012: The Lost Formula | June 10 | June 12 | 2011 | FOTD Home |
Fractal visionaries and enthusiasts:
I
am currently in
the process of dredging up old formulas. I have forgotten
what
many of them were supposed to do, and even worse, I have also forgotten
how to make some of them draw anything at all.
Today's formula is dated 14 years ago, and its name, 'MixUp', implies
that it failed to do what I intended. (If I had kept notes, I
would have known what it was supposed to do.) But it does
draw
fractals, some of which resemble those created by the MandAutoCritInZ
formula. Today's image lies in one of these fractals.
The parent fractal is a Mandelbrot set rotated 90 degrees, with the
west side facing north. A large new bay lies beyond East
Valley,
and the whole thing is surrounded by some very distorted
minibrots. The scene of today's image is on the
north-pointing
main spike, between two large distorted minibrots.
The rating of a 7 is merely adequate. The image as a whole is
eminently forgettable. The name "The Lost Formula" refers to
the
generating formula, which lay unused for 14 years, and likely will lay
unused at least 14 more.
The calculation time of 1-1/2 minutes will pass quickly enough.
Hazy sun, higher humidity, and a temperature of 86F 30C made today a
typical midsummer day here at Fractal Central. The fractal
cats
must have felt the humidity, for they spent the afternoon stretched out
on the cool tile floor. The humans had an uneventful day of
it. The next FOTD will be posted before long. Until
then,
take care, and be of stout heart but slim body.
