Mac automator

I'm still rather new to Mac, being a life-long PC guy I just recently bought a 27" iMac i5 (I do also have a MacBook I bought a couple years ago, but haven't don't much with). Anyway, one app that I'd really like to learn more about and see more examples of things you can do is the "Mac Animator." I've seen a few short tutorials on Youtube, but was wondering of there is some place on the net where a person could really get to learn this application and how to use it well?
