ABSTRACT:
The invention provides systems and methods for generating a visual image that is made to appear to be situated behind an architectural structure, such as a wall of a building, and is viewed through windows thereof. The image appears as an oversize object relative to the actual object. The system and method include an image recorder and/or a pre-recorded image, an image display apparatus, and a mask. Upon being projected, the image of interest is masked so that illumination falls on one or more regions of a display surface, and no illumination reaches the architectural structure outside the display region(s). Sound can be provided as required to complete the illusion. The image can be a still image or a moving image. In some embodiments, two viewers can see the image from opposite sides of the structure, each perceiving the image as being on the side opposite to the viewer.
