Doing some reading online about tessellations; found this little snippet from this site. The dual of a tessellation is formed by connect the centers of the shapes in a tessellation so that these segments do not pass through a vertex of the tessellation. The dual tessellations of the regular tessellations are themselves regular tessellations. However, the duals of the semi-regular tessellations are not semi-regular tessellations. So, now I know the official way to discover the dual of the tessellations I am folding. Helpful!

Found this great site via Hideo Komatsu’s blog; he’s a veritable linkfarm of new origami material. Whoever this person is, they have a delightful eye for folding animals, and capturing their essence without unnecessarily complex models. Here’s one of a small bear with salmon: From what I could translate on the description, it sounds like the bear and the salmon are two separate pieces of paper, stuck together with tape. UPDATE: fixed some of the broken link nonsense that was going on with this post. Sorry about that. I’ll do better doublechecking in the future.

Floor pattern nb 5, backlit Originally uploaded by Melisande*. Another great design from Mélisande. I think it has p1 symmetry, since a simple translation of the two basic shapes tiles the plane. although it can be rotated 180 degrees- which I think is p2 symmetry- and also tile the plane; but you have to start with a different polygon set for that. If there’s someone out there that understands this a bit better I am all ears. Please enlighten me!

Cerberus made in november, 2005. Yet another impressive work from Kamiya.
