A lenticular image (Wikipedia) is really a set of two or more images printed on, or refracted through, a sawtooth surface so that one image appears to change to another as an observer passes by. Flickr user Reasonably Clever Chris created a Lego version of the effect with a mosaic composed mostly of element number 50746, known among blockheads as “The Cheese Slope.” Check the vid to watch the transition, which happens about 35 seconds in.
