He's a fascinating personae indeed. I had a collection of short stories by him many years ago that I read. I've also been picking up on whatever I can find of Cthulhu related stuff in popular culture, for example games like Shadow of the Comet or Dark Corners of the World to movies like the semi-recent
Dagon, the retro-horror
The Call of Cthulhu or more Lovecraft inpspired stuff like
In the Mouth of Madness.
I'm of course also quite fond of the Re-Animator series of movies
Basically, the Cthulhu myth or setting is the one fantasy horror setting which scares me the most. Lovecraft was supposedly inspired by his nightmares. What nightmares he must've had! I really would like to read more from him.
