A Game Of Life

This is my tribute to the Game of Life, also known simply as "Life", is a cellular automaton created by the British mathematician John Horton Conway in 1970.
The "game" is a zero-player game, that is its evolution is determined by its initial state.
Further modifications are allowed in this version I made.
One interacts with the Game of Life by creating cell configurations and observing how they evolve or by creating patterns with particular properties. Rules are simple:

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