(game of life, brian's brain...) available in PDF, illustrated with a program (CAV) and an applet which show the capability of a conway CA to manage boolean functions as part of a Turing machine(LogiCell).
A cellular automata tutorial that covers the structure, behaviour and some applications of CA and offers a philosophical background as well; by Alexander Schatten.
Links to sites containing applets for various CA: Conway's game of life, Bays' 3-D life, triangular CA and life objects, and some new games of life that have been discovered in the hexagonal and pentagonal tessellations.
