Huffman Tessellations

I have no evidence on this score, but I strongly suspect that David Huffman first explored the tessellations on this page.  Here are some electronically published works of his, and I'm sure you will note the similarity to what I have here.  At any rate, you might think I've got some nerve calling these fold tessellations ... but each is closely related to a tessellation you are probably familiar with.  In each of these, a region of softly varying curvature can be collapsed into the sharp curvature of an ordinary origami fold.

The first is composed of Sine curves alternating mountain valley.  The interesting thing here is I only have to make O[N] creases (the curvy creases) to get O[N^2] domains of specific curvature.  I guess that isn't so interesting, after all. An ordinary mapfold does the same thing.  But, when you go to refold that map, you have to make sure that O[N^2] vertices are all "going the same way" whereas with this curvy strategy each and every 'vertex" gets set correctly as soon as all of the mountain/valley folds are made.  This is a bit misleading, I suppose, because there are *no* vertices in the tessellation, and the thing won't fold flat.  But, there is an incipient "flat-foldable" tessellation lurking in each one of these folds.  The tessellations below are related to those above, but have the curves resolved into traditional origami creases.  You should understand the structure of the troublewit to get the whole picture.  Shown below is an IsoArea 3D tessellation by Jared Needle, corresponding to the upper right panel above.  Also shown are waterbombic tessellations similar to the two lower panels above.  These are close to the "Magic Carpet" tessellation by Alexander Ratner.
