The 3D Doodle Kit plays stereographic tricks using the same principles as classic 3D movies, resulting in a fun and educational toy. Simply insert the red and blue pencils into the included plastic compass and start drawing. The double-lined illustration will appear three-dimensional when viewed with the included 3D glasses. The work of designer Carl Clerkin has been featured in museums around the world. Comes with instructions. For ages 5 and up.
