Sith Sheriff Brody has posted some nifty Lovecraftian vignettes over at the Replica Prop Forum. He includes the source files for some of the props used, including a cool little sigil and the cover of a vintage Arabic pocket dictionary.
Update: Well, that was a huge mistake. Unfortunately, accessing the thread requires membership. And membership is only open at certain times of the year, so there's a good chance I've managed to point you toward content you won't be able to see for months. I apologize for the needless frustration.
