Big Furniture Like a Cave This is the award-winning project won the Grand Prize of Art in Container International Competition. My idea is to hollow out the volume inside a container in order to build amorphous space like a cave. It is made of only plastic material. About 1000 sheets of the soft plastic material of 10-mm thickness were cut down in contour line form and were laminated like stratum. This is not only art but also big furniture. Because all the portions are soft like a sofa, and person who enter into this space can relax by finding the place suitable for the form of its own body.
