Artist Chris Schweizer sculpted this wonderfully inhuman Cthulhu maquette that quite consciously rejects the traditional "Ol' Squidhead", anthropomorphic depiction. I know that look is based on Lovecraft's own sketch of the statuette from "The Call of Cthulhu", but I rather like Schweizer's take on the material.
From artist Tim Baker comes this wonderful Astrolabe Book featuring a working astrolabe, quadrant, and abacus. It has a very "Dark Crystal" vibe to me, and I mean that in a good way.
If you're not already familiar with Wilum Pugmire it's difficult, bordering on impossible, to explain his place in Lovecraft fandom. The self-described "Queen of Eldritch Horror" is a one-of-a-kind personality that revels in his exuberant eccentricity and just happens to write some of the most intriguing Mythos stories in circulation. That said, my pathetic ego is immensely pleased that he mentioned his enjoyment of my faux trailer for "At the Mountains of Madness" in his latest YouTube video.
If you're anything like me, or most "Call of Cthulhu" or RPG fans for that matter, you've seen almost every runic and occult font out there. One of the problems with creating props for an audience like that is that they immediately recognize the various flavors of Tengwar or Futhark. You're constantly looking for new typefaces for scrolls and maps to keep things fresh.
