This cellular automaton is a grid of cells that evolve from generation to generation according to a set of rules of the mathematician John Conway (1937-2020). A living cell ist colored dark red, a dead one looks grey. Start with a living cross or by defining your own base patterns by clicking on the grid cells...
Conway's Rule Set 23/3
Every cell is surrounded by 8 neighbours.
Choose basic patterns and observe the development process of the generations in Conway's world. You will find different behavior. Sometimes the result is a still life or all cells die, sometimes an oscillators comes up or even a spaceship, that flies across Conways cell grid.
