This book is noteworthy for its clarity, its thoroughness, and its beauty. There is no other book on design basics that can compare to Zwimpfer's meticulous, encyclopedic compendium of the ways in which we perceive the two-dimensional space. I require it for all my Foundation students, no matter what field they end up pursuing. They find it not just useful, but eye-opening. Zwimpfer objectifies what most non-visual people would consider ineffable.What makes this book indispensable is its flawless design. As one turns the pages, the lavish use of space; the unambiguous, unadorned presentation of text; and the pacing of images all combine to provide one delight after another. Anyone thinking about a career in design--and most of those already practicing it--must own, read, and cherish this book.
