I have decided to dabble into making cellular automata. This is my first rudementary script.

For those who don’t know, cellular automata are games where there is a pixel grid and these pixels interact with other nearby pixels through a complex system of rules. Usually creating simple “life-like” cells.

This one uses three states, green, yellow, and OFF. It is not very good, but it can make some cool patterns.

Controlls:

Left-click: place green.

Right-click: place yellow.

Wheel: place OFF.

Space: Advance Steps (Can hold)

This project uses the browser extension.

I do plan to make more of these in the future but don’t take my word on it.

I love cellular automata! It’s good to see others using it. This is really creative idea, hope to see more!  
You should try and see if you can make it loop the screen!
