The document outlines 15 fundamental properties of nature that can be applied to design including: levels of scale, strong centers, boundaries, alternating repetition, positive space, good shape, local symmetries, deep interlock and ambiguity, contrast, gradients, roughness, echoes, the void, simplicity and inner calm, and not-separatedness. Examples are provided for some of the properties. The properties are presented as design principles for creating order and harmony.
