Nature is the best designer. It has everything we look for in great design; scale and proportion, harmony and unity, balance, emphasis, contrast, rhythm, texture and lasting details. If you take a minute to quietly look, there are many examples found all around us; the balance, scale and proportion of a tree, the harmony of perfect petals around the head of a daisy, contrast of black and white in cattle's hide, these are all examples of principles of design and the beauty of nature.
