Prometheus may have already hit theaters (to a $50 million opening), but the film's intriguing viral campaign continues onward.  If you're wondering what's left to uncover (other than trying to make sense of the film's various inconsistencies), hit the jump for a new video, book cover, and more.

If you stayed after the credits, you saw a link to a new website: "What Is 10.11.12?"  The page features a giant book bearing the words "What is great in man is that he is a bridge not an end," from Friedrich Nietzsche's philosophical tome Thus Spoke Zarathustra.  The page includes this excerpt from Wikipedia:

Thus Spoke Zarathustra: A Book for All and None is a philosophical novel by German philosopher Friedrich Nietzsche, composed in four parts between 1883 and 1885. Much of the work deals with ideas such as the "eternal recurrence of the same", the parable on the "death of God", and the "prophecy" of the Ãœbermensch, which were first introduced in The Gay Science.

Nietzche will finally rest easy knowing that his work is being put to work as a marketing device.

That marketing continues with a look Peter Weyland (Guy Pearce) apparently amping himself up for his TED talk by saying "I am a law only for my kind, I am no law for all."

None of this directly answers the question "What Is 10.11.12?" but my instinct tells me it's for the release date for the Prometheus Blu-ray/DVD even though the date lands on a Thursday.  The Playlist speculates that it could be a re-release of Alien, which would be so much cooler.
