Abstract
The present invention relates to an object that, in its closed configuration, rather than resembling a sculpture preferably has an essentially book-like form. In most instances the pages may be shaped but the covers of the book are flat and play an integral part in the stability of the alternative configuration adopted by the book in the open configuration. Each of the pages is also self-supporting on the binding in the open configuration, preferably also having sufficient rigidity to bear on its edge all or a substantial part of the weight of the rest of the book.
