Abstract
Abstract A three-dimensional display device having a generally hemispherical configuration with a displayed image or reflecting surface on either or both of its inner concave surface and its outer convex surface. The device includes at least three portions which are curved and angled to create the hemispherical shape and approximate the horizontal and vertical span of human peripheral vision without significant distortion. The device may be constructed as a rigid device or as a pop-up device movable between a flat folded position and an expanded hemispherical position. The pop-up may be constructed as a stand-alone device or is insertable between the pages of a magazine, greeting card, or like device. A method is provided for taking a series of photographs to be joined along shared match lines to create a composite panoramic display on the hemispherical display surface. A camera fixture is provided for taking a series of pictures according to the method of the invention. This is continuation-in-part of Ser. No. 07/219,479 filed by Arthur Alperin on July 15, 1988 entitled "Pop-Up" now U.S. Pat. No. 4,910,899.
