Room 401 takes a Punk'd approach to the horror genre, surprising unaware victims with terrifying illusions like the miraculous reattachment of severed hands, and live crabs bursting out of a man's chest. But astute viewers began noticing subliminal clues planted within the episodes by Kutcher himself, and in following the clues uncovered a tangled network of websites leading to a much larger game.

By building upon the already eerie nature of Houdini's more arcane illusions (reminiscient of the magic done in The Prestige, except for reals), those behind Room 401 have crafted a coy little game -- its lack of a clear objective only adding to the intrigue. The question of what Harry Houdini, Pope Innocent 1, and World War I have in common can't be the main mystery, but it sure is enough to drive the action forward.

And to keep viewers investigating, there's plenty of interesting content still being discovered. This odd compilation of stock footage and eerie voiceover is definitely one of the stranger clips to come out of the experience. But my favorite site may be 43475359616771.com, whose error message is more than a little deceiving. (The clue is in the arrows.)

For those interested in skipping right to the secrets, the best resource for tracking game developments can be found at the wiki 401WTF. Meanwhile, the fourth episode of Room 401 airs Tuesday night at 10 on MTV, with more clues certain to result. The game, online Watsons, is afoot.
