“Ren” is a wooden mobile which is a senseware of KORAI. It is made by using a traditional technique of assembling wooden strips without the use of nails to form various designs and patterns. “Ren” is an art piece that reflects the ripple on the surface of the water and light filtering through the trees by incorporating elements of Japanese original fittings such as shoji (room divider screen made of translucent paper and wooden lattice frames) and fusuma (sliding panels that redefine spaces within a room). By placing the wooden art piece indoors, people can sense the beautiful light that filters through between the carefully assembled wooden bars, and enjoy the beautiful shade of nature in the house.
