anaglyph (AN-uh-glif) - n., an ornament carved in low relief, such as a piece of cameo jewelry; a still or moving picture consisting of two slightly different perspectives of the same subject in contrasting colors that are superimposed on each other, producing a three-dimensional effect when viewed through two correspondingly colored filters.
Such as, most commonly, red and cyan lenses -- the colors need to be opposed, so that the eye with the red filter has the cyan filtered out, and vice versa, thus creating a stereoscopic effect. The technology was developed in the 1850s, but I'm having trouble finding when the term for the actual 3D thing got applied to a simulated 3D thing. The term itself arrived in English around 1650, from Late Latin, from Greek anáglyphos, wrought in low relief, from ana-, up + glúphein, carve out. An example:
