Naive Question - The traditional flapping bird generates a curved surface by tension. I'm sure there are others, but I don't recall them. 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. - Hank Simon
