From Parallel to Pointed with Old Red and New Blue
Method 'A' treats the space of the paper as catalog of variables. In series 007, each drawing is a matrix of lines. These lines are spaced much more densely horizontally than than vertically. The horizontal spacing is related to the vertical position on the paper. Each line is rotated around its midpoint at an angle depending on its horizontal position. The line farthest to the left is rotated 90° while the lines at the far right are rotated none. This run alternates between two pens, a moderately worn blue and a heavily worn red.
