Each page is a stereographic background for your writing or drawing. Put on the 3D specs and see your lines float above the page! The coloured filters in the 3D specs allow each eye to only see the opposite colour on the stereoscopic graph. As the brain fuses the two graphs together our focal point is pushed backwards creating the illusion of depth. As your drawing in black ink is seen by both eyes it remains at it’s normal focal distance, appearing to float above the page. Tips: – Do not draw in blue or red, black works best – Vary your viewing distance – Make sure the room is well lit. Contents: 50 x sheets to a pad 1 x 3D specs
