A pressure-sensitive light-extracting drawing surface including a light guide operable to receive a light source, wherein light is extracted from a light guide when pressure is applied to the drawing surface by a marking instrument. A resultant light-emitting drawing can be erased or can be made permanent. An optional multi-layered film disposed on the light guide allows drawings to be created in fluorescent, luminescent, phosphorescent, or photochromic colors. A background sheet containing designs may be inserted behind the light guide. The drawing surface can be embodied as a pressure-sensitive light-extracting "paper." The invention may be embodied as a drawing tablet, a drawing tablet add-on to a modular graphic display device, or a toy drawing tablet for tracing alphabets, numerals, and characters from comic books, cartoons, and movies.
