A proper voodoo house, down on the bayou.
I had a concept of a house that was completely black & white (not like the movies, I mean just black & white) with the scareactors wearing all white masks and emotionless. Something about those masks (
like these) have a disturbing calm to them. Anywho, the further you get into the house, blood would start becoming more prominent, with bodies and death everywhere. All the while, they would still have that eerie stillness to them.
