Like Ulam's lattice network, von Neumann's cellular automata are two-dimensional, with his self-replicator implemented algorithmically. : 8 Thus was born the first system of cellular automata. The driving concept of the method was to consider a liquid as a group of discrete units and calculate the motion of each based on its neighbors' behaviors. : 3 : xxix Ulam and von Neumann created a method for calculating liquid motion in the late 1950s. : 1 Ulam was the one who suggested using a discrete system for creating a reductionist model of self-replication. Neumann wrote a paper entitled "The general and logical theory of automata" for the Hixon Symposium in 1948. As he developed this design, von Neumann came to realize the great difficulty of building a self-replicating robot, and of the great cost in providing the robot with a "sea of parts" from which to build its replicant. This design is known as the kinematic model. : 1 Von Neumann's initial design was founded upon the notion of one robot building another robot.
At the same time, John von Neumann, Ulam's colleague at Los Alamos, was working on the problem of self-replicating systems. Stanislaw Ulam, while working at the Los Alamos National Laboratory in the 1940s, studied the growth of crystals, using a simple lattice network as his model. The rules continue to be applied repeatedly to create further generations. Each generation is a pure function of the preceding one. The first generation is created by applying the above rules simultaneously to every cell in the seed, live or dead births and deaths occur simultaneously, and the discrete moment at which this happens is sometimes called a tick. The initial pattern constitutes the seed of the system. Similarly, all other dead cells stay dead.
It is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970.

Maybe consider replacing OpenGL with (limited) core animation for an updated look and feel and breath fresh life into a dying Mac app."Conway game" redirects here. 3D and animations can be used if they provide valuable visual cues but I can't see why a card game needs to be entirely 3D.
We're well past the stage of being impressed by 3D for the sake of it! And it's not a bad thing to read Apple's user interface guidelines either. I'll try to find another nicer looking and more civilised Mac solitaire app. I think the asking price is fair for this many unique games but unless the user interface gets a major overhaul and refresh then I can't see myself playing it any more, even though I bought a license. You can't argue that the sheer number of solitaire variants is impressive and based on what the developer wrote here I'm sure they're all well researched and implemented. The background animations were always hideous overkill.

3 or 4 years ago I thought the OpenGL interface was kind of cool, now it just looks tacky to the max! The solitaire on Windows 7 actually looks much nicer in my opinion and has a nicer layout that is easier to play than this game.
