Sonobe module
Instuctions for making this model Below is the Sonobe unit, designed by Mitsonobu Sonobe, which I learned from Kazuyo Inoue. Above is the capped icosahedron which she made for me from this unit; you need to make about 30 units for this, but you only need six if you want to make a cube. Since this must be very well known, I'm only putting a very brief picture of how to make it. The second line of instructions gives a little more detail for the last step. Just in case you want more details than above, you can find some more diagams here and here. Kazuyo first showed me a kind of stellated icosohedron made from this unit; and there are lots more things to be made from it. Sonobe links

Platonic Solid The Platonic solids, also called the regular solids or regular polyhedra, are convex polyhedra with equivalent faces composed of congruent convex regular polygons. There are exactly five such solids (Steinhaus 1999, pp. 252-256): the cube, dodecahedron, icosahedron, octahedron, and tetrahedron, as was proved by Euclid in the last proposition of the Elements. The Platonic solids are sometimes also called "cosmic figures" (Cromwell 1997), although this term is sometimes used to refer collectively to both the Platonic solids and Kepler-Poinsot solids (Coxeter 1973). Origami is amazing - the traditional Japanese art or technique of folding paper into a variety of decorative or representational forms, as of animals or flowers.

Origami for Everyone Since this homepage is mainly thought for people who are new to the art of Origami, I spent quite a while trying to collect all the basic information you might need for making Origami models. I am always open for your options about what might be missing on my page. I know a lot of people have had problems with my description of the petal fold so I will try to create a better description for this fold which is very essential in many Origami models as soon as possible.

Math Craft Monday: Community Submissions (Plus How to Make a Modular Origami Intersecting Triangles Sculpture) Math Craft Monday: Community Submissions (Plus How to Make a Modular Origami Intersecting Triangles Sculpture) It's once again Monday, which means it's time to highlight some of the most recent community submissions posted to the Math Craft corkboard. I also thought we'd take a look at building a model that has appeared in numerous posts. It's the simplest of the intersecting plane modular origami sculptures: The WXYZ Intersecting Planes model.

Flashback: Woven Map Basket Maps can be amazing design elements, with all their intricately drawn lines and minute details. But what do you do with a regular paper map that is starting to fall apart from use? In CRAFT Volume 05, crafter Jane Patrick suggested we weave maps into baskets, a fun and interesting way to reuse castoffs and weave a little memory into a functional item. Check out her full tutorial here and pick up a back issue of CRAFT Volume 05, the Paper issue, in the Maker Shed.Woven Memory Basket Weave your vacation road maps into an attractive souvenir.

And when I saw a little picture of what appeared to be paper balls in a CB2 catalog, I thought, "I am going to make those." So the other day while Alex was writing a paper about mysterious things like polymers and flexible films and tactoids, I made a paper ball. Then I proudly announced I had created a tactoid and it was sitting on my desk.

Origami The Japanese art of paper folding is obviously geometrical in nature. Some origami masters have looked at constructing geometric figures such as regular polyhedra from paper. In the other direction, some people have begun using computers to help fold more traditional origami designs. This idea works best for tree-like structures, which can be formed by laying out the tree onto a paper square so that the vertices are well separated from each other, allowing room to fold up the remaining paper away from the tree.
