+( Copy of demos/life.tal, but with in infinite loop in the Screen vector )

+( Game Of Life:
+ Any live cell with fewer than two live neighbours dies, as if by underpopulation.
+ 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 overpopulation.
+ Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction. )
