Also known as the divine proportion, is a number, or a ratio, sometimes approximated by phi and widely considered aesthetically pleasing. The golden ratio has been featured in nature and art in many ways, including hexagonal honeycombs, the human body, and mathematics. More frequently, it is used in design and digital art to represent a path (or steps) one can take to achieve a particular look or result. In art, an artist may produce something (a painting or drawing, for example) using the golden ratio as a basis for its composition.
