P-10, "random walk", computer generated algorithmic plotter drawings, ink on paper, (2x) 50cm x 35cm, 1969

© 1969 by Manfred Mohr

About the algorithm:
A random walk of 100 alternating horizontal and vertical lines within an enclosed space is shown. The horizontal lines have a high percentage of a thicker width. The two drawings above show a continuous path, where lines change direction when they hit an edge of the space. The other two drawings (in the catalog) show broken paths which restart at a different position when they hit an edge.
