designer's own words:Cycle path network of Seoul has very independent and unique formation. Han River which is located in the center of the Seoul becomes the central axis and it has the network along with and around. This is totalled 728.76km long. The shape of this special geographic environment and system is very similar to a molecule structure which is consisted of a major atom and minor atoms. Individual major and minor atoms perform their own functions and these make synergy as one great system when they are merged. This connection to each other is significant to exist. Like the molecule composition, the whole network branches exist based on the main line of Han River and this unique formation of cycle path network of Seoul becomes an identity. I designed the 'Molecule' with the identity of Han River's molecule system. Body frame means major atom and the other parts connected to the body frame means minor atom. Each individual parts perform different roles, but when they are all together with the body frame, they perform a complete function as a cycle. The whole connection to each other means the cycle path network of Seoul.
