Four Similar

Here are four new images from my Small Programs series. They were developed with mostly common code. As usual, I generate the unit cell with a small program. The program randomly varies the resulting pattern. I like to consider this technique an extension of plane symmetry or wallpaper groups in that instead of translating, rotating, or reflecting the primitive cell, the small program regenerates a varying image each cell. This gives me control over the total image. For example, I did a series of three entitled "Lessness", I, II and III, with clumped images in the center, in a grid, and along diagonal rows. In the first image below the program generates sparse cells toward the center.
