Introduction I’ve been folding paper for most of my life. The first thing I remember is making paper boats and airplanes with my father. As a kid I checked out the origami books at my local library, and fairly quickly worked my way through all that I could find. Whenever a new one came out I devoured it. Origami was only one among a number of creative pursuits, however. Eventually my primary creative focus became music, playing synthesizers and saxophones in rock and jazz groups. Years later, with a new baby in the house it was time to take a break from playing out with bands, and I needed a focus for my creative energy. My first convention in 2001 was a revelation. Origami had evolved in the last decade or so. People were folding realistic models of great complexity at a very high level of execution. It totally blew my mind. But the best thing was I met a whole bunch of origami people. I’d only ever folded by myself, and had never known anyone who was into origami. They turned out to be the nicest people, smart and creative and eager to share. I took a class on origami design and by the end I’d created my Lizard and was off and running inventing models. If you’re a folder you already understand the appeal of origami as an art form, its elegant and essential nature, the joy of creating something out of almost nothing, just a piece of paper and some creases. Yet somehow this gives rise to almost limitless possibilities. Like music, origami has a deep basis in mathematics, particularly geometry and ratios, and from this arises higher levels of freeform expression. Unlike most art forms, which are either additive or subtractive with the medium and materials, origami is purely transformative. Nothing is added or removed, only changed. One endlessly fascinating question in origami is symmetry. Traditional models all use 22.5-degree symmetry, which is easy to develop and fine as far
as it goes. But why can’t the paper also waltz? One feature of my work is the use of alternate geometries, one-sixth and one-fifth, and polar or rotational-based symmetries. I enjoy complex models, but don’t like complexity for its own sake. Origami to me is a balance between simplicity and complexity, and the creative process centers on what aspects of a subject to emphasize and what to leave out. These models can be folded from a single square, most from a six- or ten-inch sheet. Although they can be made from foil or wet-folded to bring out the sculptural aspects, it isn’t necessary. My own tendency as a sculptor has been towards larger sheets (12 or 15 inch) of thicker paper. Many of these models work quite well folded out of papers like Canson, Wyndstone, or Tant. So here it is, my first collection of models. Happy folding! John Szinger www.zingorigami.com •••
