[accessibleimage] Origami question

Hi,
I have some questions about origami. 
Does anyone have any experience with using origami to teach about
geometry? 
What about using origami for making models for the visually impaired? I
came across Robert Lang's site. 
The models he made were very complex and detailed and thought that this
might be a way to produce 3-D models by other means

Does anyone know books, articles ?
Any thoughts on the subject?

Best,
Lisa
