A desktop (28) based projector screen having an inner concave display surface (30) upon which a video image (20) or a series of images is projected (23) with a sense of realism comparable with natural viewing of a three-dimensional physical reality. The viewing surface combines three concave sections which are derived from solid figures including a dome (30), a semicylindrical wall section (22) and a semicircular floor section (25).
