Conway's Life Versión 2

Simulates Conway's Life on a 20x20 grid, though you should be able to alter the grid size to something larger if you want in the script. On a Homestead region it might run too slowly for the effect to work properly.

Released in March 2015.

Update 2023-01-09:
Made it faster and added more features, including the ability to paste in a pattern and change the color. There's also a version with 5 land impact.
