Ahhh, you want genuine creeps. read H.P.Lovecraft and discover where a lot of the truly dark visions of Swiss artist H.R.Giger were inspired by...with a hefty does of uniquely Euroccult twist.

BTW: You *really* want the creeps. H.R.Giger, whose coinage and visualization of *biomechannics* in the 1970's single-handedly altered the "look" of science fiction cinema for generations to come .has a private gallery/museum in Chur,Switzerland of all of his important works
including a shrine to his famous "Alien".
There is also a private Giger Room gallery of a sort in Manhattan
at the Limelight.

However the *Real Horrowshow* is not so much the works themselves "by themselves" but the creepshow of *afficianadoes* and sophistos de Macabre that ador his work.

That's a creepshow i make no bones about that i just assume steer clear of.
