ABSTRACT:
A lampshade has a body with a number of spaced-apart apertures extending through the thickness of the body. The apertures are arranged in a pattern defining an image on the lampshade. Each aperture is sufficiently small in cross section to form an illuminated image pixel from normal viewing distances when the lampshade is illuminated by a lamp.
