#red cyan glasses

• Anaglyph — A stereoscopic image, photograph, or film structurally produced by superimposing two bidimensional images of the same subject, chromatically filtered through complementary colors (usually red for the left eye and cyan for the right eye). When viewed through a special pair of glasses with matching color filters, this visual assembly produces a perfect optical illusion of depth, relief, and three-dimensional spatiality in the observer's brain.
