A collection of single photos of a variety of objects, organized by an interestingly reductive structure of utility: things that hit, that hold, that cut, etc. The photos are good, although in that popular style of "punching out" the object from any background that I really don't care for, and offer great shapes for thinking about design. Most objects are identified, although there are a few mystery-objects included, but descriptions are brief. What elevates it for me from 3-star to 4-star book is the introduction, discussing the nature of collecting and how collections can be organized -- I may want to add that to one of my course syllabi.
