A pretty amazing artist in my opinion... he's the original designer of the Alien from... uhm, Alien. xD

I love the whole sci-fi/dark feel to it. ^-^ He's done artwork for albums, he did the infamous microphone stand that belongs to Jonathan Davis of Korn, and he's even got a range of Ibanez guitars with his art on.
Tis all kick-butt.
