Each piece is its own algorithm. Not variations on a theme — distinct works under the same roof.
THE ASKING — Two particle systems discover they're drawing the same shape.
ALMOST UNDERSTANDS — Two grids of fine lines. Where they overlap, something appears that exists in neither one alone.
SUBSTRATE — Lines grow from cracks, branching where they meet resistance.
KINSHIP (DENSE) — A flow field seen up close.
KINSHIP (SPARSE) — The same terrain, from further away.
ROOT SYSTEM — An L-system grows into perlin noise soil. Roots thicken where the ground resists.
PROOF — Rule 30. The simplest rule that no one can prove is random.
