Game of Life

Although similar to the original Game of Life, the rules of these cellular automata allow cell state to take a continuous value between 0 and 1. Furthermore, the cell state depends on the state of its 6 neighbours, using averages and thresholds. Time remains discrete generations, and exhibits looping (cyclicity) after some initial sequence (depending on the initial conditions and the threshold values).

Wikipedia:
The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970.

The game is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an initial configuration and observing how it evolves, or, for advanced players, by creating patterns with particular properties.
