One embodiment of the invention comprises a chamber having a paraboloidal top portion and a paraboloidal bottom portion, securely attached together. The internal surface of both the top portion and the bottom portion of the chamber is coated with a reflective material in order to produce an optical and acoustical illusion of a 3-dimensional image and sound of a human life-size object positioned inside the chamber. Another embodiment of the invention comprises an integral reflection-type hologram having both horizontal and vertical parallaxes, and projecting an orthoscopic real image perpendicularly from the floor in order to produce an optical illusion of a human life-size 3-dimensional image. This invention relates to optical and acoustical illusion devices, and the principal use of the invention is for optical and acoustical illusion.
