I am hosting a "funeral home" themed party this year and I typically decorate each room in the house as though it is part of a haunted house walk-through. I am hoping to convert the whole kitchen into a morgue/embalming room. It really would be cool to make the entire room flicker with a greenish/bluish light source. Is this something I can purchase? Or do I need to create the light source to cause the flickering? I am open to both options and would love to see an video tutorials if it is something I will need to create form scratch. Thanks everyone!
