This book is not traditional origami.
Jun Mitani, a Professor at Tsukuba University in Tokyo, creates small pieces of paper art with his “Spherical Origami”. Characteristic are the curved surfaces of his sculptures. The crease pattern for these models is determined by Mitani with specially developed software.
For all 21 models shown a removable template is contained in very nice natural-colored paper. The folding process is clearly described on the basis of photos. If you want to fold the models more than once, you should copy the template to a paper of your choice.
Difficulty level: easy to medium
