Summary: David Wade has spent a lifetime gathering and organizing the extraordinary families of surface patterns that nature throws up at every scale. The study of these shapes-a subject virtually unknown in the West-was known in ancient China as Li and is the sister science to Feng Shui. In this unique and insightful book are sand and wave patterns, big-cat markings, bark and leaf designs, soap and marbling swirls, crystalline and rock forms, tree branching types, and many more of nature's dynamic, sometimes enigmatic designs. Li will appeal to scientists and artists, and has far-reaching applications in graphic design, architecture, and other visual forms and sciences.
