You should really go check out John Wick's Kickstarter, Curse of the Yellow Sign.
In this collection, he's including a small but compelling Lovecraftian system called Unnamable. Based on my understanding of the current Google Doc, it has a contradiction or two...

I plan on running this system soon. I'll let you know how it goes.
