Like artwork with horrific, monstrous and fanastic themes? Looking for inspiration for a horror game? Got a few hours to spare? Then check out Monster Brains (NSFW).

It’s deliciously simple, but absolutely packed with good stuff. My favorite links include crazy-good Cthulhu paintings, charmingly unsettling Japanese art, mecha-Cerberus and one of the creepiest images I’ve seen in a long time (at least, until I saw this).

It’s a huge timesucker — I went through every month in the archives, clicking merrily away on artists that interested me. And I haven’t even started on the sidebar of links to like-minded sites! (Via Metafilter.)
