|I found one of these modular origami spheres hanging in a restaurant and searched the web until I found it at Prof. Tom Hull's modular origami web page. He invented this modular origami system. After making a few dodecahedra I decided to make a 120 unit buckysphere, a Carbon-80 equivalent shape. Many days later I finished the object on the left and it became part of my husband's company's corporate identity.|
Later, Prof. Hull put up information on making modular origami tori (donuts). I used Sarah-Marie Belcastro's octagonal fundamental unit (5 of them). Furthermore, I decided that it would only read visually as a wreath if I used three colors of green and did a three-color edge partition. This means that each edge never touches another edge of the same color. Solving a three-color edge partition for anything larger than a dodecahedron is nontrivial, so I wrote a program in Java to calculate it (Java 2 plug-in required). Or you can just grab the color diagram here.
And what's a wreath without holly berries. The berries are 2 in. red kami paper folded into waterbombs and sewn to the wreath. The wreath is made of 105 pieces of 4 3/4 in. kami paper in three shades of green.
I hung the wreath by putting a ribbon through one of the outer rim holes, looping it around the interior of the wreath, and sending it out an adjacent hole.
|This was my first attempt at one of Tom Hull's modular origami, a dodecahedron. I used 6 inch paper and it came out huge. So I suspended a crane inside it and hung it in my son's bedroom. We call it a bird cage.|
|Of course there are other kinds of modular origami. This penultimate module can make many different shapes. Most of which don't need glue! This one also has a three-color edge partition (I'm a big fan of three-color edge partitions in case you didn't know).|
|I really like Alex Bateman's Rota Coaster model. At the end of the year I like to cut up the pictures in my calendars and make coasters for my friends. But the wrap folds are very hard. After playing around for a while I discovered how to create the same coaster using simple folds only. Click here for the diagram.|
