D-Forms
$14.95
D-Forms are developable surfaces opening up new areas of mathematics, as well as many sculptural and design possibilities. D-Forms hold many surprises, and you can only appreciate them fully by making the models. Creating D-Forms is unlike most forms of model making. A pair of shapes can be joined edge-to-edge in an infinite number of ways. In this book, you can cut and assemble ten fantastic models and then use the templates included to make countless more. By John Sharp. Paperback, 8-1/4" x 11-3/4", 44 pages (2009).
