We could start with a simple lattice of squares or hexagons, then apply a set of deterministic rules—like rotate each cell by a fixed angle, scale it by a fixed factor, mirror it along one axis. Once the pattern is seeded, inject a controlled amount of noise: tweak the position of each cell by a random offset bounded by, say, 10 % of the cell size. This keeps the structure tight but lets small irregularities breathe. Add a human element by hand‑drawing highlights or smudges on selected cells, so the algorithm provides the skeleton and you inject authenticity with your brush. The rule set remains strict, but the final piece feels alive.

That’s a thoughtful refinement. Using a normal distribution for the offsets will keep the grid from collapsing into clusters, and adding a small random rotation tweak really gives each tile its own personality. You might also experiment with a subtle gradient in the noise intensity—more variation toward the edges could make the whole piece feel like it’s opening up. And when you hand‑draw the highlights, think about their placement: maybe follow the underlying pattern’s symmetry so the human touch feels intentional, not accidental. This way the algorithm’s precision and your authentic brush strokes will harmonize perfectly.
