Remember those times you entertained yourself in class making caricatures of your boring mathematics professor. Well this should make things a bit more interesting.

The paper on the pad has a special background that makes black pencil marks come alive when viewed through the accompanying classic blue-and-red spectacles. So now you can stop hunting for those 3D books and create one of your own.For more details subscribe in the email.
