" summary

Plants compute growth with simple rewriting rules and the talk shows working code: Ruby plus the beta graphics gem (SDL) runs L‑systems and turtle graphics to generate algae lines, juniper branches, artichoke and Oregon grape phyllotaxis, and drosera binata. Alan Turing’s charged‑particle model reproduces the 137.5° golden angle, implemented as a particle sim (O(N²) repulsion) and a concise one‑liner L‑system evaluator; visuals and animations render correctly and live on GitHub.
