A number of 'life' examples with different start situations, but the same rules for growth and decay. Note that the structures which grow from the center from at most four start points are all slightly different.
The structure which grows out of a number of random selected points clearly shows its origin when the structure is fully grown. On could note that centers are unaffected by growth of neighbours given my set of rules of the game.
