Cartoon Eyes Tutorial

I was looking forward to getting started on learning how to make detailed features and animation of a cartoon character. I started the tutorial on "how to make carton eyes". I actually found this surprisingly difficult as it showed how to use many features and tools that I have never heard of before. At the end of the tutorial it explained how to put a helper point target on the eye and set a rotation motion. At this point in the tutorial I got very stuck and did not understand what I was doing or why I was doing it. Setting a motion on the eye didn't seem to do anything to the eye itself and did not look like it would help with the animation. The picture below shows how far I got with this tutorial.














After this tutorial I think I may have to look into the motion panel more to find out what features are available and what they can do.
