Boids is classic artificial life program. It simulates a flock of birds by creating a number of individual agents ("boids") that each follows a simple set of rules that govern how each individual steers to maintain separation from other boids, align their direction with other boids, and try to cohere with the mass of other boids. From those simple rules very realistic flocking behaviors, like those observed in real birds, emerge.
This is a much more open-ended project than Game of Life in that there are lots of experiments you can do with even simple boids. For instance what happens when you add obstacles in the space the boids occupy that they have to avoid. Or you can elaborate the boid world. What if, for example, you make two species of boids, a predator and a prey species, where predators try to get close to prey and prey try to avoid predators.
