A simple implementation of some cellular automaton that run like a "ScreenSaver" in the terminal. This was inspired by the very popular terminal screensaver Pipes.sh

• Conway's Game of Life (life.sh)
• Wolfram's Elementary Cellular Automaton (elementary.sh)
  • Supports all 256 rules, automatically picks one when ran without arguments
  • Supports passing a rule number as an argument
  • Allows passing of -r to specify a random seed location
  • Allows passing of -t to toggle a toroidal boundary (simulates an infinite grid)

This project is MIT Licensed, all I ask is for credit in some form :)

git clone https://github.com/Liam-Wirth/Automata.sh.git
cd life.sh
chmod +x life.sh elementary.sh

./life.sh

Press any key to exit.

./elementary.sh [OPTIONS] [RULE_NUMBER]

./mazecetric.sh

./brain.sh

• -r : Use a random starting cell instead of the middle one
• -t : Use toroidal (wrap-around) boundaries
• RULE_NUMBER : Elementary CA rule (0-255). If omitted, uses a random rule

# Run with rule 30
./elementary.sh 30

# Run with rule 90 and random seed
./elementary.sh -r 90

# Run with rule 110 and toroidal boundaries
./elementary.sh -t 110

# Run with random rule, random seed, and toroidal boundaries
./elementary.sh -r -t

• These are all standalone scripts, which I like, but in the future I think it might be better to extract out common functionality (they all basically use the same skeleton, which is just pasted from the first one I wrote, life.sh) to cut down on repeated code
• Add more colors
• Add optional "picker" ui or somethin
• Add more "customization" to all of them (mazecetric, and brain don't have parameters that can be passed)
