This is a very simple turorial for beginners.

Animation can be as hard or as easy as you want it to be.

This one is easy, create two pictures with slight differences.
 
                  

    Then join them in an animation program.

                     
And there you go a simple animation that you can use for your Avatar.

For any one who does not have an animation program, then just create two images and send them to me and I will animate them for you
