I bought this from an interest in pattern and polyhedra as it is an established classic, delving into higher dimensions. I can't deny that it is classic and definitive, but it is very much a textbook aimed at those doing maths as a career or postgraduate study. For my purposes, half an hour on wikipedia was more fruitful to get a practical on-hands overview of higher dimensional polytopes.
