They belong to the flocking Alife creatures variety, sharing with them the social tendency to stick together, and the lifelike emergent behavior which is based on a few simple, local rules. They differ from most other flocking Alife animals by having the following properties:

• Predation (they must survive against predatory GOOeFloys, or survive as one)
• Ability to evolve (using the Genetic Algorithm).
• Potential individualism (each can possess a different personality through evolutionary processes)

• Adjust the overall movement by clicking the 'Slower' or 'Faster' buttons (click several times to reach the desired effect).
• Insert a predator and observe how it attacks and consumes the prey GOOeFloys.
• Click the 'Scramble' button to introduce variety in the population.
• Click 'Start Evolution' to start the evolutionary process, where each generation begins when the last predator GOOeFloy dies.
• Change the personality of the population by modifying properties in the 'Edit Properties' screen.
• Try the other buttons to see what they do. More information can be found in the GOOeFloys description page.
