Akira Yoshizawa, a teenager in the nineteen-twenties, quit his factory job and proceeded to turn paper-folding into a fine art. Today, origami kits are common and consist of a booklet of instructions and a set of colored paper. The paper is two-sided with a different color on each side. The instructions, consisting of mostly of arrows and lines, are a part of a worldwide standard of visual language for origami that Akira pioneered. He also invented the wet folding technique, which allows for more sculptural interpretations.
