April 2, 2011: An Island Universe | April 1 | April 3 | 2011 | FOTD Home |
Fractal
visionaries
and enthusiasts:
The minibrots in some fractals are connected to the main body of the
larger fractal in which they exist. The minibrots surrounding
the Mandelbrot set are all connected by thin filaments to the main body
of the M-set in this manner. Other minibrots have no
connection to the rest of their fractal, and exist as island universes,
scattered around the fractal's main body like moons frozen in time.
Today's FOTD image shows one of these disconnected minibrots.
The parent fractal is a tiny Mandelbrot set surrounded by a cloud of
minibrots, which in turn are surrounded by smaller clouds of minibrots,
etc, etc., all the way down. The image shows a minibrot near
a larger minibrot in one of these sub-clouds.
Since the larger minibrot is itself disconnected, the pattern
surrounding the minibrot in today's image consists of disconnected
patches, filled with still smaller clouds of minibrots, all of which
are well beyond resolution.
In my fractals, I usually try to avoid overly busy and brilliant
colors, but in today's image the excessively gaudy color palette
actually seems to improve the overall appearance. If I had
had more time, I might have gotten a bit more action from the
underlying iteration bands, but even as the image is, it earns its
place as FOTD for April 02.
The name "An Island Universe" tells it like it is. The image
is part of an island, and it has a universe within its
depths. The rating of a 7 is becoming so common that the FOTD
rating system is starting to become redundant.
The calculation time of a fireball 18 seconds seems too good to be
true, but take my word, the image calculates in just that time.
Another way to see the image is to view it in finished form on the
currently active FOTD web site at:

The venerable original FOTD web site is still available at:
http://www.Nahee.com/FOTD/
My own web site is almost ready. All I want to do is prepare
a proper home page with a brief introduction to the world of
fractals. I have also decided to include a gallery of several
hundred images that I saved to disks in the years before I began the
FOTD. These old images, which go back to the late 1980's,
were created with various fractal programs. Most have no
parameter information embedded. They are not up to current
standards, but they are still interesting images, showing how I
launched my fractal explorations.
Friday here at Fractal Central began with wet snow that melted as it
fell. By midday the snow had changed to rain, which slacked
off to sprinkles in mid-afternoon and ended by sunset. The
temperature reached a chilly high of 43F +6C, keeping the fractal cats
within leaping distance of the heat.
The rest of the day was filled with routine everyday stuff such as
making money. The next FOTD will likely be posted in 24
hours. Until then, take care, and if you know what a lemac
is, you're probably not a teen-ager.
