Fractal
visionaries
and enthusiasts:
Today's image lies in virtually the same parent fractal that held the
image of September 16. I say virtually the same fractal
because I
have refined the real(p2) parameter so that the parent fractal now has
perfect X-axis symmetry rather than almost perfect symmetry.
The
refinement makes no difference in the surface appearance of the parent,
but it gives a more satisfactory base to today's image, (whatever that
means). The scene of today's fractal lies in a spurious
valley of
the large minibrot on the northern of the two main spikes of the parent.
The image rates only a 6. The colors lack a certain harmony
that
could raise it to a rating of 7 or 8. And the sharply angular
shapes themselves have a vaguely threatening appearance.
The name "Caught in Flight" was the first thing that came to mind when
I stopped trying to think of a name. It has no rational
connection to the image.
The rain ended Thursday night, but dark lumpy clouds hung on all day
Friday here at Fractal Central. The temperature of 64F 18C
felt a
bit chilly, though it was not all that unpleasant. The
fractal
cats spent the day checking for unwanted stray cats in the vicinity.
My day was appropriately busy for a Friday. With the garden
well
watered, FL took it easy. Unless an unexpected antiquing trip
comes up on Saturday, the next FOTD will be posted in 24
hours.
Until whenever, take care, and take it easy.
