This is one of my favorite origami books. Some of the simpler models are really well-thought out, and I think this book shows why Lang is such a great origami designer. That golden eagle that you can see on the upper right hand corner of the cover is a really neat model as well. I also once made a really big version of his rabbit model, which is very three-dimensional, that came out really well (I had to stuff it with tape in order for it to retain its three-dimensionality). I enjoy how he really uses the third dimension in these constructions; very few of them are flat, and many of them look quite realistic. Paper choice is important when constructing these models: you want to choose paper of an appropriate size, but also consider the thickness of the paper when planning out how to make these models. I highly recommend this book to people who are interested in making three-dimensional animals out of paper. ( )
