I loved this book, as probably love or love anyone like me think the manual creation is a form of expression of the most essential of my personality. Through the construction of a toy the author take you to understand the mechanism. Then of course if we should reduce this book to a simple assembly instructions we will come to the conclusion that as is, it is unusable in the European market. But precisely understand the mechanism can be adapted to the materials available at home. This is great. And in addition it can be beautiful. From simple functional plywood we can also employ various abstract and noble essences. In conclusion I would say that between beauty and functionality the result will suit you taste.
