In August 62 I started doing silkscreens. I wanted something stronger that gave more of an assembly line effect. With silkscreening you pick a photograph, blow it up, transfer it in glue onto silk, and then roll ink across it so the ink goes through the silk but not through the glue. That way you get the same image, slightly different each time. It was all so simple quick and chancy. I was thrilled with it.

In early computer art:
In «Cubic Limit,» Mohr introduces the cube into his work as a fixed system with which signs are generated. In the first part of this work phase (1972–75), an alphabet of signs is created from the twelve lines of a cube. In some works, statistics and rotation are used in the algorithm to generate signs. In others, combinatorial, logical and additive operators generate the global and local structures of the images.

In generative art
Can you reverse engineer Every Icon?
Same principle applied to rotational symmetry:
We’ll cover more generative art in a couple of weeks…
In level design
Modular generative systems are often used in games to generate levels procedurally:
