P-128, "sphereless", plotter drawing ink on paper, 50cm x 50cm, 1972

© 1972 by Manfred Mohr

About the algorithm:
A matrix of signs is projected onto a sphere. The signs are random subsets of the four lines of a square and its two diagonals.

This drawing from 1972 using the sides of the square as an alphabet subsequently developed into the workphase "cubic limit" 1973 which uses the 12 sides of the cube as an expanded and richer alphabet.
