About the algorithms:

P-147, 1973, is one of the precursor drawings to my cubes with missing line drawings, Cubic Limit I, 1973-1975
- In each square on a very fine grid, one of the four corners is chosen randomly. In this position a triangle is drawn with 1, 2, or 3 lines.

P-129, 1972, is related to the drawing, Sphereless, P-128, 1972, in which squares with missing lines are projected onto a sphere.
- In each square on a grid, one of the four corners is chosen randomly and a solid triangle is drawn. The grid is projected onto a sphere.

P-135, 1973
- In each square on a grid, a point near the center is randomly chosen. This point together with the four sides of the square form 4 triangles.
- 0, 1, or 2 triangles of each square are chosen to be filled - the first one is filled with hash lines, the second one with solid lines. - The probability that a triangle will be filled, increases towards the bottom of the grid.

P-144, 1973
- In each square on a grid, one of the four corners is chosen randomly and a random slice of a triangle is drawn.
