摘要:
A drawing tool comprises a pair of transparent screens each defining a drawing surface on the underside thereof. A powderized etching composition is contained in a closed and sealed chamber beneath each drawing surface to fully coat the surface upon shaking of the drawing tool. An operator-controlled joy stick can be manipulated universally to simultaneously move drawing points along the drawing surfaces to scribe nearly identical two-dimensional designs thereon. An optical viewer mounted upon the screens enables the operator to stereoscopically view the individual images created by the designs as a three-dimensional image.
