Microbe Swarm is a B&W simulation of bugs flying around the screen.  You can set how many you want.  

Poly is a program for investigating polyhedral shapes. Poly can display polyhedral shapes in three main ways:  · as a three-dimensional image,  · as a flattened, two-dimensional net, and  · as a topological...

Welcome to Starry Night! Starry Night is your ticket to solar system tourism. Travel in both time and space; get a first hand experience of the intricate and beautiful clockwork of the heavens. You can see the stars and planets as they appear from...

Critters is an artificial life program for the Macintosh.  Within the universe of Critters, many Critters and Hippocritters will be born, live happy and (occasionally) meaningful lives, have children, move around, eat, and eventually die. ...

MacDoppler PRO gives you a seat right in the heart of the Operations & Command Centre for every satellite in orbit. In fact up to sixteen front row seats at the same time. With MacDopplerPRO, you get the most out of satellite...

  MotoSfera simulates the motion of a ball over a 3D surface. You can choose between three different surfaces. The best one, I guess, is sin (X^2+Y^2). Once MotoSfera is started, just set the initial speed conditions by choosing...

Vivarium is an interactive demonstration of the evolution of behaviour, displaying how behaviour adaptions tend to spread through a population of lifeforms. This artificial life simulator is quite complex. While the user can input some base...

Robot Arm is a nice B&W arm simulator that you can experiment with the mouse cursor.  Holding down the click button on the mouse grabs and releasing it releases whatever box you or object you grabbed.  Pulling the bottom/left lever...

Pagoda (Tower of Hanoi) is a Tower of Brahma simulation for very early Macs. It auto-plays until it solves the puzzle.  

Mr. Cycloid is a spirograph for 1980's early B&W Macs.  

Life Hack is a nice Game of Life simulation implementation.  It allows to draw directly on the grid using the mouse, has very fine cell resolution, can save/open, display stats, have multiple windows redrawing in parallel.  Also, it's...

LifeLab is yet another "game of life" simulator.  It works with large screen resolution as well as smaller ones and has many options to fiddle with.  You can for instance shift the whole pattern in a given direction by an...

Cellular Automata Program or simply "Automata" is a crude cell life simulation application with few options. It basically draws a continuous feed of B&W pixels.  

A 2D gravity simulator. The technology would later be used in Space Cab. The READ ME includes a few game ideas people could play within the simulation.
