I'm not usually a big fan of Duy Nguyen's origami books, as his work stretches the definition of origami in ways I'm not comfortable with. I do like this little book, however. Using only one to three US $ bills, with no cutting, Nguyen creates very nice representations of real and fictional aircraft, including Star-Trek and Battlestar Galactica spaceships. The production quality of this book, as with most of the author's books, is high, and the spiral-binding is very convenient. There are some money facts between the diagrams.

Diagram quality could use improvement. While mostly readable diagrams, a strange choice was made to use very few directional arrows in the steps. This could confuse newcomers to origami.

A fun book for those who enjoy folding their money instead of spending it on more origami books!
