Hungry Fingers Cubograph, one of the most recent additions to the Hungry Fingers collection, is probably the first resource which attempts to explain to totally blind learners drawings of 3D geometric shapes. Edges of a collapsable cube can be compared with those in a tactile drawing, helping understand why some edges are drawn with solid lines and some with dashed lines. Understanding this serves as a basis for understanding drawings of other 3D geometric shapes in a book which comes with the Hungry Fingers Cubograph.
