First of all - if you have the book: Origami - The Complete Guide to the Art of Paperfolding, Don't get Action Origami, since it's only a partial collection of models from that book. Nothing new is added. If you don't have The Complete Guide , then maybe you should consider buying it instead of Action Origami , because it adds many other nice models.

The book opens with a colorful section about the history of origami, followed by an excellent gallery of models. Next is a section about techniques (including back-coating and wet-folding) all with color photographs.

The models range in difficulty from simple to intermediate, and there are no diagrams - the instructions are all photographs with explanatory text. This can be an advantage to those having difficulty reading from diagrams, and a disadvantage to those who are used to the symbol system.
