About Inverse Kinematics
by Joseph Burchett on Dec.03, 2008, under Developers, Joseph Burchett
Inverse kinematics: “is the process of determining the parameters of a jointed flexible object (a kinematic chain) in order to achieve a desired pose. Inverse kinematics is a type of motion planning. Inverse kinematics are also relevant to game programming and 3D animation, where a common use is making sure game characters connect physically to the world, such as feet landing firmly on top of terrain.” Id say Wikipedia sums it up pretty clearly 
It takes a bit to load… Please wait.
It’s funny how you see this sort of thing a lot in games, and in flash cartoons… but never really hear it talked about that much. The example below is something I snagged from a blog where this guy creates a demo which shows you exactly what Inverse Kinematics is all about! Give it a go.. It’s some pretty fascinating stuff.

As of Flash CS4 Inverse Kinematics functionality is built into the IDE and you can do it from with in code to.
Although this tutorial is for a much older version of flash… the concepts still remain the same, and I am sure you could apply this logic to just about any other language. So if you are interested id take a look at http://www.gotoandplay.it/_articles/2004/12/inverseKinematics.php
