For me it was the mausoleum facade. I had large doorway (with no door) that needed blocking off so this was my solution. It's not completely set up in this picture, we also put a white tarp behind the spiderweb lace curtain and had a strobe flashing behind it. It was the largest thing in the room so when people came in their eyes were drawn to it. They couldn't get over the fact that I had a "mausoleum" in the room.
