Typical of his early algorithmic work, this piece links line to language, process and conceptual systems. Mohr calculated the image using a program that he authored in the FORTRAN language. With a choice of different line characteristics, an alphabet of randomly generated elements is created.
More about the algorithm:
Lines with acute angles represent the numbers 0-9, and lines with obtuse angles represent the letters of the alphabet A-Z. When a letter adjoins a number, a horizontal thick line is added between them. The space between the line is thus formed and a lower base horizontal line is filled in with parallel vertical lines. In P-142 letters and numbers are chosen randomly, thus creating a random text.
