 ## Conway's Game of Life (Fast)
 This example demonstrates a fast and efficient implementation of Conway's Game of Life using the [`PropertyLayer`](https://github.com/projectmesa/mesa/pull/1898) from the Mesa framework.

 ### Overview
 Conway's [Game of Life](https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life) is a classic cellular automaton where each cell on a grid can either be alive or dead. The state of each cell changes over time based on a set of simple rules that depend on the number of alive neighbors.
