Takeo Kanade extended the Huffman/Clowes/Waltz line and junction-labeling 
idea to origami figures.  The application here is not graphics,
but image interpretation: given a perfect line drawing of a polyhedron
or an origami figure, label the line segments as convex, concave, or
occluding edges.  Constraints between edges incident on a junction
yields only a few consistent labelings.  The labeling yields
some shape information.

I like folded paper best when it's green and has pictures of former Presidents
and lots of zeros on it ;-) .
