Zombies are the new vampires.
Just noticed that the University of Alabama has this itunes U podcast course. "why the familiarity of zombies makes them scarier and more fun to study" including: "She's Not Your Mother Anymore" and "The Living as Minority."
All free, of course. I love da internet! and my ipods!
also, a quick Google of "zombies" throws up some pretty interesting stuff. If you're into that.
