If you are as fascinated with the graphics of Escher as I am, you’ll be entertained, amazed and engrossed with this ‘kit’ which allows you to assemble and hold these wonderful models of intriguing mathematics, coupled with the graphic art and figures of the master himself, M.C. Escher. It is one thing to look at Escher’s magnificent work in 2-dimension but it is another experience entirely, to hold these 3-dimensional models and view the figures and patterns as you turn and fold these models on themselves. One of the other reviewers talked about creating additional models and that is obviously possible because there is all the information needed to do that, right here in the book. I have had this kit for some time but hadn’t actually constructed any of the models. I recently was told about a man who constructed ball and stick models. I contacted him and visited him to see his models. I brought along with me a book, “Polyhedron Models” by Magnus Wenninger. The M. C. Escher Kaleidocycles is an outstanding book covering the subject as well as 119 models. The man I was visiting had the book and even knew its author. This book deals with models whose surfaces are flat and made of cardboard or if desired, other materials. To see what these fascinating models look like, look them up on the net under “Magnus Wenninger”. The man I visited constructs similar models but uses only wooden balls and sticks. Think of those chemistry models of compounds and you can imagine how beautiful and interesting they can be. All models begin with one of the known uniform polyhedra and from them the stellated models are formed. The variations are in the many millions. Anyone who has much interest in this sort of stuff will find an excellent chapter, Polyhedra, in “Mathematical Recreations and Essays” by W.W. Rouse Ball, a real classic in the subject of Mathematical Recreations. The man I went to visit has been working on these models for many, many years. He has created his own techniques and even an intriguing apparatus to make the holes in the balls. The exactness is so critical, that making them by hand would be terribly difficult. To date he has made about 500 of these ball and stick models. So, after my visit, it was a real joy to sit down and construct some models. You can purchase this book at Amazon.
