February 18, 2012: Triangulation | Feb. 17 | Feb. 19 | 2011 | FOTD Home |
Fractal visionaries and enthusiasts:
In
most of the
fractal calendars I have seen, almost every image is filled with
spirals of various sizes and shapes. I have never quite
understood this fascination with spirals, but there must nevertheless
be something attractive about them, so in today's image I have featured
a spiral.
Not wanting to merely go along with the crowd, I have cast aside the
countless circular spirals that fill almost every fractal and found a
spiral triangle. I found the weird spiral lurking on the west
edge of the extra bay in the East Valley of the parent fractal of the
'leaves' image that appeared two days ago. I found no signs
of
minibrots in this area, but the triangular stuff I did find, partly
obscured as it is by clumps of detached elephant trunks and spotted
with smaller triangles, made an image worth being declared
FOTD.
The triangular spiral is a bit subtle, so the image must be studied
before the spiral effect becomes obvious.
The rating of an 8 is based mostly on the mathematical
interest.
As a work of fractal art, the image rates more like a 6-1/2.
The
name "Triangulation" is self-explanatory. The calculation
time of
5 minutes borders on unacceptable slowness. To escape the
boring
calculation, check the FOTD web sites.
The day began sunny here at Fractal Central, bringing hope of an
afternoon in the sun to the hearts of the fractal cats. But
clouds moved in by midday, dashing their hopes. The
temperature
of 50F +10C was mild enough however to blunt their disappointment.
The humans, FL and I, added a bit of interest to the day by taking an
antiquing expedition down to Lemoyne, PA, a city across the river from
Harrisburg, where FL found a new lamp table. The next FOTD
will
be posted in 24 hours. Until then, take care, and every day
someone finds another health hazard. It seems that to end the
constant worry about health, we will need to totally eliminate all
disease, aging, accidents and finally death itself. Then
there
will be nothing to worry about but over-population.
