"When we found that there was a device, a plotter which could draw lines, and a device, a computer, which could perform the calculations for driving the plotter resulting in lines which I only partly thought of beforehand, we found a very exciting but very difficult drawing medium. Using a computer-plotter extends my hand-eye-head. The computer draws, my eyes see, my hand draws, the computer is programmed by Jeff, the computer draws...in an endless productive cycle. Computer drawn lines enrich my hand lines which in turn enrich my computer drawn lines..."
"A field has no center, and is not really flat, so I use no flat areas. The form of grass as grass, leaves as leaves, is what I’m exploring…Line as form. Grass as form. Grass is also random and random is a natural computer facility. Computer grass is natural grass."
"without conscious understanding of what a drawing is we could not use the computer as a drawing medium…We ask this new medium questions and get new (and old) answers. But some of the answers were there from the beginning."
"Jeff and I have been making two-dimensional art for a long time. Ive been making paintings and drawings since childhood and was educated as an artist. Jeff has been thinking what mathematicians think and writing it down since childhood and was educated as a mathematician and as an artist. In the 1960s Jeff became involved with computers and their programming and with using the computer to help people solve their problems."
"When the University of Kansas was given a plotter in 1967, Jeff was asked to test it. We began to think of drawing lines with it in ways that we found visually interesting. Together, we had enough common background and experience to begin to use the computer graphically. Together we draw with the computer and sign the drawings ."
"The subject of all my work has been landscape. The elements of both the computer work and my hand work are often repetitive, like leaves, trees, grass and other natural landscape elements are. There is sameness and similarity, yet everything is changing. Landscape yields both texture and form. The pictorial form is usually all-over, with non-focus details which form patterns, since I feel these as essential properties of landscape. A field has no center, and is not really flat, so I use no flat areas. The form of grass as grass, leaves as leaves, is what Im exploring."
"Jeff and I use the computer as a traditional drawing medium. The resulting drawings are to be seen, to hang on a wall, to communicate. They are not just examples of computer technology, not just geometry, not just mathematics. We ask this new medium questions and get new (and old) answers. But some of the answers were there from the beginning...landscape. That it is possible to use mathematical formalism and pure geometry while attempting a humanistic exploration to us is one of the primary advantages of the use of the computer as a drawing medium."
