WaTor World X is a Mac OS X version of the predator-prey type simulation originally described in Scientific American by A.K. Dewdney. Sharks eat fish, fish eat algae, and algae grows on empty space. Fish and sharks die and breed after a specified number of generations. The parameters can be dynamically changed during the simulation. This is my first Cocoa application, so it's possible there's memory leaks or other problems. Constructive criticism is appreciated.
