P-142, "negative field syntax", computer generated algorithmic plotter drawing, ink on paper, 50cm x 50cm, 1973

About the algorithm:
Lines with acute angles represent the numbers 0-9.
Lines with obtuse angles represent the letters of the alphabet A-Z. When a letter ajoins a number a horizontal thick line is added between them.
The space between the line thus formed and a lower base horizontal line is filled in with parallel vertical lines.
In P142 letters and numbers are chosen randomly, thus creating a random text.
