Seigaiha without cuts

Seigaiha (lit. wave of the blue ocean) is one of the designs found in Hiden Senbazuru Orikata. This model is the uncut version of it. In theory, one could repeat the pattern and folding method of this model to fold even a thousand orizuru from a single sheet. This model was designed independently and is different from a few similar designs previously proposed by others (such as the "Crane on a Plane" by Robert J. Lang and the "Zuru Tessellation" by S Taro), most notably by having developed a fully linear folding sequence without complicated "single-step collapsing".
