PHI: The Golden Ratio or Golden Section - a unique Ratio (or relationship between parts) that seems to be preferred by Nature as the best geometry for growth, energy conservation, elegance and has some fundamental relationships to the platonic solids and the Mandelbrot set. It was formally discovered by the Greeks and incorporated into their art and architecture, but it has been shown to occur even in prehistoric art, possibly as a function of Man's natural affinity for it's beauty.
From my native homeland. The curled Ponga (Tree Fern) koru. The koru is the budlike beginning of a fern leaf before it opens. The symbol is prominent in traditional Maori art motifs such as bone and wood carvings, and tattoos (moko). The unfurling koru leaf pattern represents new beginnings.
