Cool stuff!
Reminds me of a haunted house I went to a few years ago. Not an actual haunted house, just some trailers that were set up in the parking lot of a shopping mall over Halloween.
Anyway, one of the rooms was painted black and had all these designs painted all over it in neon. I walked into the room, and waited for the scary/creepy but nothing happened. All of a sudden I saw something move out of the corner of my eye, and I turned and saw this woman dressed in a black cat suit with the same designs painted on it walking toward me. It looked like she materialized out of thin air! I nearly peed myself, LOL. After a moment, I realized that she must have been there the whole time, she was just very well camouflaged against the wall.
