I was looking towards creating a crystal ball, with a talking woman inside, which consists of filming a person, casting a wax form of a person's head, purchasing a round aquarium, putting the wax form inside and projecting the recorded individual into the wax'ed persons head from behind the fishbowl, which creates the same effect as Disney's Haunted Mansion. Did anyone try this, and can they add any knowlege to this concept?
