During my sophomore year of college, I discovered one of the most effective means of wasting time, modular origami. The basis of my earliest pieces of modular origami was something called the “penultimate” module. I'll leave the explanation to Jim Plank, from whose site I learned of modular origami. The main relevant fact for me was that the most natural and basic penultimate module lent itself to the construction of a dodecahedron out of 30 pieces of colorful notepaper. Although it's corny to say, the dodecahedron holds a special place in my heart among geometric solids. My father used to teach his students to make dodecahedra by cutting out and gluing together 12 regular pentagons. I made a lot of those when I was a kid, but I always yearned for a more satisfying construction technique, preferably without the inconvenience of glue that can dry before all of the parts are aligned. The penultimate module did the trick, and variants of it can be used to produce a huge variety of forms, some of which are shown in the pictures below. In fact, everything currently shown except for the gift box is based on a variant of the penultimate module.

Somewhat more recently, I played around a bit with more traditional origami, specializing for a time on the Kawasaki Rose (the blue image in the upper right corner of all of my pages is a manipulated image of one of these). I've been meaning to put up some new images, but that will have to wait until I have some more free time.
