Here's a simple book I coded for use as an icon (rendered small, so not much
in the way of detail). The leather-bound cover lies flat in the XZ plane,
and I've only used four pages (two on each side) - you could either use many
more copies of the patch object to create extra pages, or perhaps define a
prism using the same Bezier co-ordinates to represent a whole block of
pages. Untransformed the book is about <4.4, 0.8, 2.8> units in size.
