It is true - you will never look at another door handle or tap(faucet)in the same light after reading this book. The main problem I have is that this book itself is not particularly well designed! For a start the title on the cover is in an odd font, in capitals, and with strange shadowing - together making in difficult to read. The text is poorly spaced on the pages. The sub-chapter headings are not indexed or numbered, but seem to follow an undefined order according to font size and placement on the page. Consequently it is difficult to follow the flow and structure of the ideas being presented. Large tracts of the text are in Italics, but it is not clear what this is supposed to signify. Footnotes on each page rather than at the end of the book would reduce the amount of flipping back and forth required of the reader. The photographs seem to be taken by an amateur. They are rather murky and lack detail, and are not helped by the almost newsprint-quality paper used in the book. Sometimes (in the case of photograph 6.6) it is impossible to even make out the feature being discussed in the caption. In almost every case, lengthy captions are required to explain the accompanying diagram. Surely a principle of good design is that illustrations should need no explanation. Don't get me wrong, this is an interesting and amusing book that is still worth reading... it is just a shame the author did not apply some of more of his design standards to the book itself.
