ARG: Marble Hornets

I've been watching an ARG (Alternate Reality Game) called Marble Hornets for a while, and I thought I'd share it with the weirdos that read my blog, I kid, I kid, Just one of you is a weirdo. You know who you are. Anyway, it's based on the "Slender Man" legend which is, in turn, based on a German being called "Der Großmann." It's basically a malevolent being of the woods that kidnaps, causes insanity, stalks its victims, and a whole bunch of other unpleasant stuff. Below is the fist video of the series. It's very well done, and had me convinced it was until recently... and I'm still not completely dissuaded.
