It is a sort of cellular automation game where a template is used to alter the pattern of tiles on a grid. The rules and components are very simple and there has been no analysis or proof of solvability or maximum number of moves required or how whether size of grid affects the number of turns required. Some patterns are self-solving and these might be quite common. All fertile ground. -- PETER FOX Not the same since the adhesive company came unstuck 2 Tees Close, Witham, Essex. p@eminent.demon.co.uk Gravity beer in Essex
