2D Game of Life — Flat Cellular Automaton

This is the flat, top-down companion to the 3D Game of Life simulator. It runs the exact same B3/S23-family rules on a wrap-around grid, but draws every cell as a plain flat square with no camera, height or rotation — click or drag to toggle cells by hand, load classic patterns like the glider or Gosper glider gun, and watch generations advance at any speed.
