This was my very first computer graphic image I considered an original work of art. Both figures were initially drawn by hand, transferred to graph paper then converted to a list of coordinate pairs. Care was taken to make sure each figure had the same number of points and lifted the plotter pen in the same location. …

This drawing uses the Goose figure from a set of hand-digitized representational images. The full set consists of: Goose, Frog, Fat Cat and Elephant. I often used these interchangeable figures in my early works. Digitized representational image of a Goose is placed at intervals along a space curve. …

Boxes I is a generative art "derivative" piece inspired by one of the earliest pioneers of the generative art medium, George Nees. In the beginning when we only had plotters to draw lines with, the small community of computer artists produced works that inspired each other. His work called “Gravel” inspired me to create Boxes I and Boxes II. …

A regular grid of square tiles. As the computer draws each square its position relative to the center of the grid is calculated using the distance formula. In the case of Boxes II the further the square is from the center of the grid, the more random displacement (translation) and rotation is allowed. …

An Op Art inspired work. Bulges and Dents is a two tile tessellation where each tile is a tessellation. In one tessellated tile a mathematical function manipulates the drawing coordinates of a regular grid of tiles to appear to be pushed in (dents) while the other manipulates the drawing coordinates of a regular grid of tiles to appear to be pushed out (bulges). …

This drawing uses the Goose figure from a set of hand-digitized representational images. The full set consists of: Goose, Frog, Fat Cat and Elephant. I often used these interchangeable figures in my early works. Coming and Going is the juxtaposition of two spiral configurations. …

This is regular grid tessellation made up of 9 columns x 7 rows of tiles. Each tile is an interpolation between a smaller inner square and the larger outer square that contains it. The number of in-betweens in this variation is fixed and the position of the small, contained square is allowed to vary. …

This is regular grid tessellation made up of 9 columns x 7 rows of tiles. Each tile is an interpolation between a smaller inner square and the larger outer square that contains it. The number of in-betweens in this variation is random. The position of the small, contained square is allowed to vary (translate) horizontally and vertically by controlled randomness.

This drawing uses all the figures from a set of hand-digitized representational images. I used to be an Engineering graphics professor. Back in the day, before CAD, we were developing algorithms for perspective drawing. In this piece I wrote an algorithm to randomly distribute my digital menagerie on the surface of a cylinder. …

This drawing uses the Elephant figure from a set of hand-digitized representational images. Digitized representational image of an Elephant is placed at intervals along a space curve. Curves are generated by a mathematical function written by Christopher Scussel. The Elephant’s scale and orientation is based on data from the curve. …

This drawing uses the Frog figure from a set of hand-digitized representational images. Frog Pond is an original work from around 1975. It is a very simple algorithm. A predetermined number of digitized frog figures are distributed about a center point using a random angle (0 – 359 degrees) and radius (a random polar coordinate). …

This drawing uses the Goose figure from a set of hand-digitized representational images. Geese is an original work from around 1975. The computer generates an array of translation coordinates and translates each goose into position. A mathematical function written by Christopher Scussel provides the rotation angle for each instance of the goose in its respective position in the array. …

Horizons was an image intended as a wedding present for friends. The couple were Mormons and seagulls have some significance to them in their faith. At the time I wasn’t quite sure what marriage was about, but it seemed to me that it was about a commitment as a couple to move off together into the future. To me the future lies on the horizon. …

Hard to believe these two images have survived so long. The printer was one of the first computer output devices. When you ran a program on a computer in the early 1970’s you always got the output on printer paper. The paper was cheap and plentiful. …

Historically, some of the first computer graphics were printer outputs made by arranging alphanumeric characters on printer pages. Computer nerds would figure out which characters to print to make Snoopy or Star Trek characters. They also figured out how to produce gray scales by overstriking characters. It was crude but effective. …

Kolomyjec’s Moiré was my attempt at making an Algorithmic Art contribution to the Op Art Movement. It is a mandala-like image that seems to pulsate as you observe it due to the Gestalt phenomena of figure-ground. Twelve equal-length, equal-spaced lines radiate from the center. …

le Morté de Beardsley is a carefully designed image. I wanted to pay homage to Aubrey Beardley based on a Dover book of his illustrations. I was very inspired by his illustrations and wanted to introduce some of his style into my nascent medium. …

A regular grid of square tiles. Each tile consists of a square with its perimeter divided into the same number of points of the circle it contains. Randomness determines the placement of the circles’ center relative to the center of the square. The method by which the points between the two shapes are connected creates a 3D illusion.

The is regular grid tessellation made up of 9 column x 7 rows of tiles. Each tile is an interpolation between a smaller inner square and the larger outer square that contains it. The number of in-betweens in this variation is random. The position of the small contained square is allowed to vary (translate) horizontally and vertically by controlled randomness.

The scorpion is a hand-digitized figure taken from a woven rug purchased on a vacation to Greece. Later in graduate school I used the image from the rug as subject matter for this generative art piece. A computer algorithm used the digitized scorpion image data in a controlled random way. …

This is an early work. It is a regular grid tessellation where each “tile” consists of two randomly generated overlapping ellipse shapes. Each shape is made of the same number of points. Rather than connecting the points (coordinates) that define the ellipse shapes’ perimeter, I connect one ellipses’ perimeter points to the corresponding point in the second ellipse, and so on. …

This is a simple regular grid tessellation; the tiles are either a twinkling star or a moon in one of its phases from full to almost new. A coin-toss algorithm is employed to decide on which shape is drawn. If the star is chosen then controlled randomness determines a star’s inner radius, the outer radius being fixed. That is as close as I could get to making a star twinkle. …

M.C. Escher demonstrated this algorithm by employing traditional media and interlocking figures in his “square limit” graphic works. I don’t claim to be on par with Escher but I had a computer to do my drawing. I devised an algorithm (described below) and designed two interlocking hand-digitized figures: an angel representing good and a bat-devil representing evil. …

I had the idea to do a bird-fish transformation with digitized data. I already had a hand-digitized figure of a Seagull from another project, so I designed and hand-digitized the representational image of a Walleye. (Why? I used to go fishing for Walleye with my cousin.) …

This was a proof of concept drawing of an algorithm I created for changing one image into another, where I stored all the line segments that make up an image (in this case a set of vertical and horizontal lines) into two arrays. Think of it as two bags of line segments. …

This was a surprising variation of one of my earliest Generative Art pieces, Organic Illusion. Organic Illusion is a regular grid of square tiles. Each tile consists of a square with its perimeter divided into the same number of points of the circle it contains. Randomness determines the placement of the circles’ center relative to the center of the square. …

A variation of Banana-Cone. Linear interpolation between two digitized representational images. One figure, the bunch of grapes, is placed inside the other, the water droplet. The outline of the water droplet is not continuous; rather it is made up of the same number of points as the grape figure. I.e., carefully contrived. …

A regular tessellation of overlapping “tiles.” The tiles alternate. The form of the tiles are two variations of a circle. Each circle is comprised of vertical or horizontal line segments which are clipped by the outline of a circle. The line segment spacing, or intervals, are determined by a trigonometric function. …
