1. A method of creating a final image which, when displayed at a target location, is perceived by viewers as being three dimensional, comprising the steps of: (i) selecting a target location for the display at a display site; (ii) capturing video of at least one object to be displayed in the final image, the at least one object moving in the video at a necessary perceptual speed by translating generally along a plane extending through the eyes of expected viewers and/or rotating generally about an axis perpendicular to said plane; (iii) displaying the final image at the site onto a transparent screen positioned such that the final image appears at the target location in front of a background and such that the movement of the at least one object at the perceptual speed occurs.
