In 2003 I created my Vampire Room Scene. By using 2 4'x8' sheets of plywood I made a giant skull with eyes that lit up (using x-mas lights with a sheet stapled behind each eye this glowed with the x-mas lights)
Guests would enter this scene through the skulls mouth. Upon entering this scene you would see coffins, candleabras, stained glass windows (made from a large piece of cardboard and red transparent gift "basket" wrap that gave a red glow), fog, in one of the coffins there was a pop up ghoul. The fog came out of the large entrance skulls mouth when people moved the shredded plastic to enter the scene - pretty cool effect. The only lighting in this room was the candleabras and the glowing stained glass windows.
