i shall speak only for myself with this list but musicaly...
devin townsend, fear factory, korn, latter deftones, meshuggah, neurosis, godflesh, mear tri, sephiroth, blut aus nord, megaptera, esoteric, red harvest, bjork, portis head, Dj shadow, massive attack, left feild, akira yamaoka silent hill
.s.t. 1 -4, and a whole load of stuff i cant remeber right now!
Other media, silent hill 1 - 4, project zero, the suffering (all ps2 games) david lynch movies, whole variety of japanese cinema - anime and other wise, ramsey campbell short stories, H.P. Lovecraft, Transformers, but most of all our home town (the inspiration to local lad Ridely scott for a lot of his sci fi work, blade runner ect) and its inhabitants but the biggest most over powering influence to us at all is the little insideous voice, more distant than the furthest star and closer than the thickness of a shadow, that says 'i wonder what would happen if you recorded that noise, slowed it down and played it backwards...'
