Cyclic cellular automaton

A cyclic cellular automaton is like playing a game with a group of friends. It works by starting with a group of cells, which are like little squares. Each cell can be one of many colors.

You can think of it like a game of checkers. In checkers, you can jump over your opponent's pieces and capture them. Similarly, in a cyclic cellular automaton, each cell can “jump” to the next cell (like a checker piece jumping to the next space). The colors of the cells get changed with every “jump.”

For example, if the first cell is red, it “jumps” to the next cell and turns it blue. Then, the second cell will “jump” to the third cell and turn it yellow. This pattern keeps repeating until all the cells have changed colors.

In this way, the colors of the cells keep cycling between a set of colors, which is how this type of automaton gets its name.
