Monolith room (@Bocam), blue background (@Kaburorne,@QKT) and the black Fez logo (@bananas) as per your request, and a special one I really wanted for my own desktop (took me quite a while this one, liked the idea of Gomez living inside a computer screen ;).
@ImmortalSaiyan: An alternate reality game (ARG) is an interactive narrative that uses the real world as a platform and uses transmedia to deliver a story that may be altered by participants' ideas or actions.
@drowsap: I'm spooked as well, definitely not stopping now though! How awesome would it be if an ARG was the big idea al along? This game has been in production for so long... Maybe there's more stuff in Indie Game: The Movie as well?
