"I am positive he did too much LSD in the 60's (albeit teh 1560's)." Sorry to be the party pooper, but that popular notion (hallucinogenic ergot fungus) and the other, that Bosch was a madman, are totally baseless. His imagery was typical for depictions of the Christian Hell in his time and place. Many other Flanders artists of that time depicted similar demons and freakish scenes. Bosch was just the best of 'em. :-) At first I thought you meant that Dali took LSD in the 1960s, which is true. As a child, several of the films already mentioned spooked me. Also an episode of Outer Limits (or was it The Twilight Zone?) called "The Zanti Misfits" which featured creatures with antlike bodies and humanoid heads with lots of teeth. Oh, and there was that awful early '70s TV movie with Karen Black and the little African idol who comes to life and goes on a stabbing spree...can't remember the title, but it scared lots of people. As a young adult, yeah, The Exorcist, The Shining, and the original version of The Haunting, mostly for not showing "monsters." The soundtrack in Exorcist is scarier than the images.
