It can be hard to find great live visualizations of the Genetic Algorithm, which is a popular and well studied method for providing adaptation to a Complex Adaptive System, but this is a superb example. Created by Rafael Matsunaga, this “Genetic Algorithm 2-D Car Thingy” simulation takes polygons of varying parameters (initialized randomly) and gives each two “wheels” of varying sizes. All of the “cars” are dropped in to the environment and the most fit cars are selected for the next round.
Genetic Galaxy Defender is a simple space shooter game written in Flash where you play a heroic space pilot defending your motherland from the horde of invading alien robots (that, for some reason, look like Octopi). This is a game I made for a final project in a Systems Engineering class where we focused on biological inspiration in engineering design.
