A figure used in many Asian cultures to symbolize the unity of the two ``opposite'' male and female elements, the ``yin'' and ``yang.'' The solid and hollow parts composing the symbol are similar and combine to make a Circle. Each part consists of two equal oppositely oriented Semicircles of radius 1/2 joined at their edges, plus a Semicircle of radius 1 joining the other edges.
