Summary

Javascript port of Scriptbots (https://sites.google.com/site/scriptbotsevo/) Requires a copy of the Sylvester Vector math library (sylvester.js) in the same directory as Life.js and Worker.js To use: For a list of default parameters see: https://github.com/JimAllanson/lifejs/wiki/Default-Parameters For a demonstration, see: http://jimallanson.github.com/lifejs/ For more information on the simulation, see: https://sites.google.com/site/scriptbotsevo/ For a copy of the Sylvester library, see: http://sylvester.jcoglan.com/

What This Teaches

  • How a complex idea can be compressed into a minimal but working implementation.
  • Useful as a reference style for serious small systems rather than decorative demos.

Why It Matters

This matters as part of Karpathy’s broader pattern: compress hard technical systems into readable, inspectable, working artifacts.
