This paper reviews the concept of cellular automata and describes a simple way to implement them in APL2. Two cellular automata are programmed: the well-known Conway's game of life, and one that simulates an ecosystem and displays a behaviour similar to that represented by the Volterra differential equations. Cellular automata are shown to be a powerful simulation tool for this kind of systems.
