There is a graphic novel simply titled Lovecraft that is not so much adapted from any of his works, but it is a fictionalized account of his life, and of course he manages to slip through the cracks of reality into a Lovecraftian dimension, where a few tentacled beaties wait for him. I liked it a lot.

That's Lovecraft's wife in the bottom right... she plays a part in the story, too.
