P-133, "cluster phobia", plotter drawing ink on paper, 50cm x 50cm, 1972

About the algorithm:
This drawing is a visual random printed circuit. The idea is to divide space and match non-intersecting elements to fit. In each column, there is a high percentage of empty space. The first step is to lay down the surfaces. This is done by randomly generating pairs of horizontally oriented broken lines which are each filled with horizontal and vertical grid lines. The second step is to fit rectangles (active white and passive black contacts) into the created indents. The third step is to generate horizontally oriented broken lines to fit around the existing elements. These lines can be repeated if the space permits.
