Handmade ink, prolly done in 1983: Computer generated: Cantor City Starting with a certain number of a basic shapes (here: 3 rectangles), new lines with more cells are added. The color of a new cell is a function of the color of its ancestors. The resulting pic is mirrored. Cellular automaton patterns: In a classic cellular automat, cell value is either 0 or 1; black or white. So I made one, that doesn't work that way but allows for a greyscale: Yeah, I know, ornament is crime. I blame the algorithm.
