[NEohioPAL] Lovecraftian Horror Makeup?

So with Halloween coming up at the end of the month, I've decided to start doing research early for once. Are there any makeup artists out there who know how to look, well, H.P. Lovecraft-y? As in like tumors, misshapen necrotic flesh, tentacles, eyes where there's not supposed to be eyes, et cetera? Just wondering what's out there. Thanks in advance.
