This is a simple project using Godot C#.
It follows the rules detailed in the wiki article. Conway's Game of Life - Wikipedia
Right now, it randomly generates cells with a 50% chance of being alive or dead, and then runs.
When a cell lives long enough it will become lighter, to show the cells that have been there the longest. Dead cells slowly fade away in a nice way.
The whole project runs from a single scene, node and script file all called Root. Script parameters are exported to allow for experimentation in the node editor.
