paperfolder and origami theorist who is known for his geometrically innovative models. He is particularly famous for his series of fourfold symmetry "roses", all based on a twisting maneuver that allows the petals to seem to curl out from the center of the flower. Kawasaki also teaches mathematics at Sasebo Technical Junior College. Kawasaki new rose

Kawasaki was the first to develop the technique of iso-area folding, which allows the folder to end up with each side of the paper displayed in equal amounts. It consists of building a mirror-symmetrical

crease pattern A crease pattern is an origami diagram that consists of all or most of the creases in the final model, rendered into one image. This is useful for diagramming complex and super-complex models, where the model is often not simple enough to diagram e ...

and then collapsing it to find a finished form, usually a geometric shape such as a cube. He also discovered and proved that with any given flat point in an origami model, the sum of alternating angles is always equal to 180 degrees, a result now known as Kawasaki's theorem.
