Life: Birth and Death

This is a fun life game and a "zero player" game.

Here we have prepared a grid for you, where players can design some patterns. By placing the "cells" in different positions, the final shape of the "cells" was observed.

rule:

Any live cell with fewer than two live neighbours dies, as if caused by under-population.
Any live cell with two or three live neighbours lives on to the next generation.
Any live cell with more than three live neighbours dies, as if by over-population.
Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.
