Movable cellular automata is like a board game, but instead of regular squares or pieces, you use tiny computers, or "cells". Each of these cells is programmed with a special set of instructions, and each cell can be moved around on the board. Every time a cell moves, it follows the instructions it is programmed with, and when multiple cells come into contact with each other, they interact with each other based on the instructions they are each programmed with. This means that the cells can work together to solve puzzles, play games, and do other things.
