December 6, 2011: Blobs and Things | Dec. 5 | Dec. 7 | 2011 | FOTD Home |
Fractal visionaries and enthusiasts:
Today's
image is the
fourth consecutive one with a rating of 8-1/2. All right,
maybe
I'm pushing the rating a bit, but it's still a pretty good image, with
lots of angular contrasts in the strongly colored vaguely egg-shaped
patches surrounding the central minibrot.
The parent fractal was created by subtracting Z^(0.7) from Z^(0.5),
then adding straight C on each iteration. This parent is a
Mandeloid rotated 180 degrees, so that its East Valley is on the west
side of its main bay. Much unexpected detail lies in this
East
Valley area, consisting mostly of disconnected pieces of fractal stuff
floating in a networked sea of ever-smaller pieces. Today's
image
lies in this east detail, which is actually on the west side of its
parent.
The largest bud of the parent, which lies along the positive X-axis, is
even more striking than the East Valley (west) area. Instead
of
the expected near circular shape, this bud has the rough outline of a
violin, with large sub-buds on the north and south shore
lines.
The stuff normally found beyond the large bud along the main spike is
missing. The bud terminates at a very large valley, with only
unknown emptiness beyond.
As a possible home of minibrots, this violin-shaped bud is equally as
interesting as the East Valley area of the parent, and will be checked
more closely in tomorrow's FOTD.
The name "Blobs and Things" refers not only to the blob-filled image
but also makes a comment on the names often given to the trendy but
near useless stores that fill the main streets of small towns soon
after a Wal-Mart opens nearby.
I created the colors with a single stroke of the <enter>
key,
which brought up a palette of intense but narrow bands of colors
alternating with near-black bands. In today's image it works
quite well.
The calculation time of 1-1/4 minutes will pass swiftly once the top of
the image appears and anticipation surges. Preparing a
parameter
file from this letter is a minor hassle however, but this is where the
web sites come in handy.
Heavy clouds and occasional rain made the high temperature of 57F 14C
here at Fractal Central today less enjoyable than it otherwise would
have been. The fractal cats found no joy in the outside
conditions, turning instead to their food bowls for happiness.
Humans such as FL and I require slightly more sophisticated things for
our happiness however, so our day turned out merely average.
The
next in the long string of FOTD images will appear in 24 hours and is
likely to be another with a rating of 8-1/2. Until then, take
care, and if life serves you a lime, trade it for a lemon and make
lemonade.
