Abstract
A drawing tool comprises a pair of light transmitting screens, a ground beneath each screen, and a former or tip under each screen adapted to either add material to the ground or subtract material from the ground to create a design thereon. The designs are viewed as a composite three-dimensional image and can be permanently fixed on a removable plate.
