Friday Fractal XXX*

i-4cc79b6021b24a472b504704485181a2-gfwhole.jpgMany things in nature seem to catch our eye, simply by hovering between a turbulent, chaotic mess, and a vacant, serene sense of order. Art tends to reflect these dichotomies in nature, even when it is fairly abstract in nature. Some say it stems from a fascination from good and evil, or light and dark, or lightness and weight. But I suspect we just enjoy exploring the point in between. This is the draw of fractal art... the edge of the fractal itself, the border between the "inside" and the "outside" of the shape, can be followed endlessly. To our eye, the wonders and variation never seem to cease.

This is a layered fractal, based on a torus-shaped "Juliabrot" (what happens when you leave the Julia set alone with the Mandelbrot set and a bottle of wine, perhaps?) But this is only the first shape with a complex edge; another set of variables controls the coloring used to fill in the complex edge of the first. This coloring algorithm chooses exactly how to fill in the pixel, based on a relationship between a trap placed on the complex plane and an orbit around that trap. This is further amplified by the coloring algorithm recalculating new directions every time a new pixel is placed. Just in case there wasn't enough tug between balance and chaos, both the coloring algorithm and the separate plasma background are based on fractal Brownian motion... essentially, yet another layer seeking the boundary between order and chaos. Remarkably, somehow all of these rather chaotic variables manage to converge in harmonic waves:

...an effect similar to, but not quite as complex as, the harmonic waves seen in a plunging waterfall:

The image on the left shows a "zoomed-in" shot of both the fractal and the photo. Which is the waterfall? I'll reveal the answer next Friday.

(*) Note for anyone who was hoping that Friday Fractal XXX might be a different sort of fractal, i.e., not one suitable for younger viewers: I will admit, I run across all sorts of natural forms while creating fractals. Some of them might even raise... an eyebrow. But this week, I wanted to post a waterfall... so, if you were hoping for a naughtier fractal than usual, you're out of luck. Unless you click here.

As a writer, I love to use metaphors to explain what I see. Sometimes, it is much easier to describe how something is like another thing than it is to describe the thing itself. The metaphor adds a subjective layer of context to a thing, making the unfamiliar familiar. Language is, in some part,…
Note from your fractalist: Sorry, folks, this one is a day late. I discovered early yesterday that my old website had been hacked. It has been fixed, now, although I plan to eventually remove everything from there, and repost it here somewhere. Just getting the bad scripts out has kept me plenty…
Fractals, like so many sights in nature, can seem both static and dynamic at the same time. A cloud can change its shape right before your eyes, and so can a slice of the Mandelbrot set, with a slight nudge of the bailout values. Try to find the same spot later on, without the same exact values,…
Life is complex. The last week has been particularly so for me, but I’d rather not go into details about it. So, I’m keeping this week’s fractal somewhat on the simple side. I suppose in fractals, just like life, simplicity and complexity are often found side by side. I’ve always liked to describe…

Did you see the little link I snuck in at the end? I suppose you never know what might be hiding behind the waterfall. ;)
