In this fascinating book, designer and critic Jessica Helfand offers and in-depth look at these unique artifacts, which are not only clever and amusing-where else could you dial-in ingredients to concoct "Creamed Oysters and Celery"?-but, Helfand argues, relevant as a model for modern interactive design. From circular mathematical slide rules to Captain Marvel phonetic decoders; from nuclear bomb blast calculators to gestational breeding planners; and from astronomical planispheres to presidential trivia plotters, Reinventing the Wheel demonstrates the astonishing range and remarkable utility of these ingenious "interactive" tools.
