Lens Tessellation, designed by David Huffman

The Lens Tessellation is an example of curved-crease origami.  A relatively simple example of curved creases–so simple that a paper explaining the basic mathematics of curved creasing uses this model as a case study.  To make this model, I used a ruler and compass to draw out lines, a hand-cut stencil to copy patterns, and a ceramic stylus as a scoring tool.  I walked through some curved crease methods here.

Something I learned from the math paper, is that this crease pattern has multiple conformations.  If you poke and jab at the paper in the right spots, you can switch its conformation.  I have a photo below, where the left side is in one conformation, and the right side is in another conformation.  You can see the difference in the pattern of shadows on each side.  On the left side, the ripples of paper are horizontal, while on the right side, the ripples are oriented diagonally.
