Hi, first time trying to make a haunted house for the comunity center here, I have seen a very cool see through ghost at another haunted house, and although I have a rough idea on how to make it, I'm still missing something... How do I make a holographic ghost? The one I have seen was a little boy who could actually turn, look at the people passing by and react (silently) to their coments... How do I do that? Where do I put my actor and what kind of glass do I need? (where can I get that?) Any help would be great.
