"Now I am beginning to see what a line is about. To see that I can choose to draw little lines, a one big sweep of the arm line, a coiled or an uncoiled line, crossing lines, spiraled lines, decorative lines, random lines, and it's all the same line. Where and how these lines are placed and colored make the drawing what it is, that composition is perhaps the truly difficult element in the making of a drawing. Now I have really to think about what I am doing while drawing in order for Jeff to write a program to deal with what I can do as second nature. This thinking has made the making of the hand work much clearer. We consider each drawing element as an independent element. This is artificial. Yet, this artificiality is precisely one aspect of the use of a mathematical attitude—the separation and isolation of individual elements of a problem. Our computer graphic efforts have shown us just how complex even the most simple meaningful hand made drawing is. In addition to making drawings using the computer, we appear to be finding out just what the making of a drawing is about regardless of its medium."
