Carl Liu: Taiji Chopsticks. The concept of yin yang, is used to describe how polar opposites or contrary forces are interconnected and interdependent. Opposites only exist in relation to each other. Yin yang are complementary opposites that interact within a greater whole as part of a dynamic system. Taiji Chopsticks are two identical chopsticks representing yin and yang. The spiral design on the top enable two chopsticks to intersect each other and form dynamic balance and endless energy.
