| This simple stationery set will play stereographic tricks in your minds eye. Using the same principles as those 3D movies, the brain is tricked into creating an illusion of depth in your 2D scribblings. A fun and educational novelty for all ages.
"The 10.5cm compass style instrument allows images to be drawn in duplicate red and blue lines which must be a small but constant distance apart. This has the effect of lifting the design off the page and giving it depth when viewed through the special 3D glasses provided."
