Show HN: Scanner for cellular automata rule space

Category: devtools

Tags: cellular-automata, simulation, rule-search, visualization, canvas

Score: 5.0/10 (Innovation: 5, Technical: 6, Documentation: 6, Utility: 4)

An interactive browser-based explorer for one-dimensional cellular automata that supports arbitrary state counts, neighborhoods, and temporal depths. It allows manual rule definition (totalistic, template, descendant, random) and automated scanning of rule spaces to tag interesting behaviors like gliders, chaos, and periodic patterns. The tool is useful for CA researchers and enthusiasts to discover and analyze complex rules.

Target audience: researchers, hobbyists, educators in complex systems and computer science
