Has anyone written a paper that categorizes this type of model with 'non-creased' curved surfaces ? [The flapping bird is an exception to this category, but the only example that comes immediately to mind. I think Jackson, Wu, and others may have static 'curved tension' models.
In one of Paul Jackson's books, there is a Phillip Shen Pentagonal Flower, which uses tension to create petals that are slightly curved. Leong Cheng Chit also has quite a few curved tension models on his flickr site. In fact he's come up with some sort of categorisation for the different folds. http://www.flickr.com/photos/chengchit/920470628/in/photostream Winnie
