Build an undersea world that contains a clownfish and a shark. Build a swim() method that makes each kind of fish swim forward 1 meter in a more or less realistic fashion. Build a program containing a scene in which a shark chases the clownfish and the clownfish swims to its giant cousin, a clownfish, which chases the shark away.
