Yin Yang by Fan Fun
Draw an ancient version of the Yin-Yang symbol by concentric half rings. Change their number or modify their constellations in time to have fun with this fan.[more]
The legendary sage king, Fu Shi, would have set the number of rings to 3 and time to +.5 or -.5 in order to obtain his symbol for opposites that transform into each other.[less]
