The Game of 'Life' in PostScript

Do you know the game of "Life"? The game was created by mathematician John Conway and described in this 1970 Scientific American article. Based on a small set of rules, the game looks at the initial configuration of a set of counters (representing "organisms") and moves them forward through time. Certain arrangements result in life, while others perish. The coolest implementation of this game is one in PostScript. Remember PostScript is a programming language, although it's mainly used to format documents. There's a Java version and another here.
