predator and prey populations grow exponentially. The predator
(red squares moving vertical) needs to eat prey (moving horizotal)
in order to grow. So the population growth rate of the predator
depends upon the prey density. When all prey individuals have
been removed, the predator individuals starve and their population
decreases. The prey population grows back faster than the predator.
The system stays dynamic without any outer influence. After the
system has been disturbed, by user interaction for example, it
will allways fall back to its original rhythm.
