About

This ecological simulation shows the shifting balance between grass and rabbits. Initially, there is only one rabbit and the grass grows quickly. When the rabbit has eaten enough grass, it spawns another rabbit which may, when it has eaten enough, spawn new rabbits itself. Soon there are many rabbits eating grass and the grass cannot grow fast enough, resulting in overgrazing. Rabbits that don’t manage to eat enough grass die (turn black, then disappear). As the rabbit population declines, the grass is able to regrow and the cycle begins again.
