''Motion Capture translates motions into 3D-files and are used in this project to simply record the tip of a pen when people draw pieces of furniture in the air. Rapid Prototyping is a technique that materializes 3D-files. A laser beam builds the 3D-file layer by layer within a liquid plastic material. Every 0.1mm the liquid harden by a laser beam. After a few hours, the 3D-files come out as materialized pieces. The Sketch Furniture project in Japan is made in collaboration with Barry Friedman Ltd. Tokyo Wonder Site Aoyama and Crescent.''
