How to design and Simulate Swimming Fish using the .NET - Free Source Code

In one of my Articles I showed you on How to Design Language Translator, Text-To-Speech (Speech Synthesis) with Microsoft Translator Services, today I'm going to show you how to Design and Simulate Swimming Fish.
What I meant by simulate swimming fish, is that, how to write a program to make a fish swim water. i.e in a lay man's understanding.

Technology - Visual studio 2010
Language - C#
Topic - How to Simulate Swimming Fish
