I also gifted myself an Arduino (Leonardo/Micro) over the holidays and have had a lot of fun working through the basic exercises and thinking up imaginative ways to use it.

Check out this Arduino for Beginners (In Comic Form) - probably particularly good for those of you who gifted an Arduino to children, and links to other resources in the last panels.
