Origami Koi Fish

The most recent origami from Lang’s book Origami Design Secrets: Mathematical Methods for an Ancient Art that I have folded is the koi fish. It was fun to make. It looks complicated, but it isn’t. Lang does show how to make scales, which you can implement on the koi. However, this makes it much more complex and time-consuming, so I started with just the non-scaled koi.

I might try to make some scales on a plain piece of paper, just to learn how to do them. If they are easy enough, then I might try folding a new koi with scales.

Complex Origami

My wife gave me an origami book for Christmas: Origami Design Secrets: Mathematical Methods for an Ancient Art by Robert Lang. It has many folding instructions for some very cool designs. What really stands out about this book is what its subtitle suggests: “Mathematical Methods for an Ancient Art.” That’s right, Lang has gone to the effort to explain why certain folds are used and the mathematical theory behind them. This can result in some very complex designs. Some really amazing things he explains are how to make scales that cover a fish’s body, and how to make long, thin appendages (like for a tarantula.) Every design uses a single piece of paper (sometimes large, sometimes non-square) without any cuts or adhesives. Continue reading Complex Origami
