A reflective projection screen has in a first aspect a plurality of reflective elements. The upper surface of the reflective elements is either coated or textured to interfere with reflection of light from the upper surface to an adjacent reflective element. In a second aspect of the invention, a screen is provided that reflects light in the vertical direction like a plane surface, while reflecting light in the horizontal direction back toward the light source. In a third aspect of the invention, a projection system projects a three-dimensional image.
