Your task is to build a cellular automaton using the rules of Conway’s game of life that will allow for the playing of a game of Tetris.
The underlying idea of this project is abstraction. Rather than develop a Tetris game in Life directly, we slowly ratcheted up the abstraction in a series of steps. At each layer, we get further away from the difficulties of Life and closer to the construction of a computer that is as easy to program as any other.
