### About the Artist

Gregory B. Searle is a digital computer artist with a Bachelor in Fine Arts from the University of Lowell (now U-Mass at Lowell) and a computer programming background. He combines these seemingly opposing skill-sets to create unique computer-generated “fractal” imagery using his own custom computer code. This allows him to explore a whole world of mathematically-generated imagery, carefully crafting the limitless parameters to produce one-of-a-kind, high-quality fractal prints.

At this time he is exploring trigonometric variations of the *Mandelbrot*,
*Tower of Powers*, and *Newton* fractals at various real exponents.
The combination of formulas, trig functions, fractional exponents, and different
rendering techniques provides a limitless world of form and texture to explore.
The expressive forms that emerge are enhanced by low-saturation or purely grayscale
color schemes, highlighting shading, texture, and motion.

### About this Site

This page is intended as a space to explore computer-generated *fractal*
imagery as an art form. See the *About Fractals* page for more information.

### New Artwork

*Carousel*
*Curtain Call*
*Misty Landscape*

Reminiscent of the lights on a ride around the merry-go-round, “Carousel” is a deep zoom into negative exponents. Pitting tangent against arctangent under frequency-counting produces a complicated interaction of lights and bursts.

The logarithm function creates patterns all on its own. “Curtain Call” has the exponent set to near unity, 1.1. Swoops and folds look like curtains draping on a stage in infinite patterns.

The cosine function tends to generate ripple-and-wind effects. “Misty Landscape” is a mild magnification of a vertical slice just under the exponent of 2, with cosine applied and a linear render method. Mist-covered mountains await in the background.

### New “Fractal” - Unity

Creating a Mandelbrot variation with an exponent of one (or unity) seems silly, until you modify it with trigonometry.
The base formula, *z=z+c*, is fast, allowing the calculation to concentrate on the trig functions. In this image
the logarithm function adds mechanical curves and straight lines, giving the impression of “Microcircuitry.”

### New Artwork

There are multiple methods to depict a fractal rendering. “Flight” one uses *angular cycle counting*
to measure how rapidly each point changes. The result was unexpected. This is a fairly deep zoom into
the *Negabrot* (exponent of -2) using this technique. There is a lot of energy in this image.

An orderly progression of chromed surfaces resulting from a mild zoom into the multibrot set at a fractional
exponent below 2 with an Exponential function applied produces a fairly imposing image in “Order.” It is somewhat...
*Orwellian*... I attempt to title my pieces with words that reflect not only what appears to be
there, but how they *feel*.

### New Fractal - Newton

*Newton*

The *Newton* fractal illustrates the chaotic nature of the *Newton method* for iteratively
discovering the roots of a complex equation. By default, it renders in the Julia set, but things get interesting using
other rendering options. This fractal is essentially a Multibrot formula divided by its derivative.

### Trigonometric Variants

New functionality in my *Fractal Everywhere* software allows trigonometric
functions to be injected into the Multibrot formula. “Synergy” is a slice
through Multibrot space with sine and tangent functions applied. The greyscale scheme
allows the subtle shading and forms to take precedence.

### Julia Set

*Julia of Mandelbrot Cubed*

The *Julia Set* renders Mandelbrot variants a little differently.
Using a reference point in the set, it renders against this point to produce a fairly
regular, symmetrical fractal shape. It's not quite as complex as the base set, but
can produce some beautiful imagery. Fractal Everywhere
now supports Julias. Click on “Julia” next to the formula menu to render
the Julia for the currently displayed coordinates. This acts as a toggle, so you can
switch back-and-forth. It's available for all fractals.

### New Fractal - Tower of Powers

*Tower of Powers*

*Multibrot at 1,000 Expoent*

*Tower of Powers* calculates the initial value *c*
raised to the power of the result *z* over and over again, *z = c ^{z}*,
starting with

*z = 1*. You would think that this would quickly escape to infinity, but there are some stable areas that produce interesting results. This is very similar to what appears when you render the Multibrot with a very high exponent. For more information see Cleve Moler's article on the subject. Check it out in my Fractal Everywhere.

*Fear of the Dark* comes from the fragmented space in the negative exponents around -1.5.
Dark and mysterious, it has a lot of interesting things going on in the details. Check out the page for more.

### “Special Merit” and “Special Recognition”

*Clematis* received Special Merit and *Equinox* received Special Recognition in the the March 2018 Light Space & Time
Online Art Gallery's 9th Annual Abstracts Art Exhibition. Following are a couple of excerpts from
the gallery:

“The gallery received 952 entries from 29 different countries from around the world. In addition, the gallery received entries from 40 different states.”

“The gallery also included Special Merit awards and Special Recognition awards for outstanding art. Many of the artists in either of these groups could have easily been included in the upper tier of our winners, as their art was also exceptional.”
