Heard of Nat. Geo's "The Genographic Project"?

Apparently you pay about $100 and Nat. Geo sends you a packet with some cotton swabs. You swab the inside of your cheeks and send it back. In return, you should receive information about your Ancestors and where they came from! Isn’t this interesting?

Has anyone done this before? If not, are you interesting in trying it out? I know I am.
