this is a recreation of conway's game of life in scratch. the rules are that there are cells which are "dead" or "alive". for one turn, if an alive cell has 2 or 3 alive neighbours, it stays alive, if a dead cell has exactly 3 alive neighbours, it becomes alive, and if neither is true, the cell dies. click on a cell to switch its state (alive/dead), and use the "run" button to run the automaton
