http://www.lulu.com/shop/bruce-rawles/sacred-geometry-design-sourcebook-universal-dimensional-patterns/paperback/product-6202693.html

A "coloring book for kids of all ages", there are 27 3-dimensional "fold-up" patterns which make it easier than ever before to create exquisite shapes revered by pioneers such as Plato, Pythagoras, and Leonardo daVinci. There is a brief introductory section on the philosophical perspective of universal proportions and symbols. The book also has extensive tables, World Wide Web links and bibliographic references for those whose interest and curiosity has been sparked by the hands-on, experiential majority of the book.
