A piece of ulexite (TV stone) placed on a watercolor of a mountain.  The natural fibers of ulexite conduct light along their long axes, by internal reflection such that ulexite functions much like a fiber optic cable bringing the watercolor image to the surface of the stone when viewed face on. Viewed from the side, the illusion disappears.
