Jorge had asked on April 22 about a design issue he believed he read in Robert Lang's "Origami Design Secrets" that resulted in more models having an open back.
I'm not sure what you mean by open back. I browsed the term and found it used regarding both animals and tessellations. Does it refer to the same thing in both cases? I think I get what it means in relation to animals. This traditional penguin must be an example: http://www.origami-make.org/traditional-origami-penguin.php I don't see how can that also be the case in regards to tessellations =S Is the penguins open back what you meant with your question? Can you please explain to me the concept? Thanks in advance Jorge. Gerardo gerardo(a)neorigami.com
