IN-EI - Japanese for "shadow, shadiness, nuance". This new process was developed using a mathematical program with 3-D geometric principals by Jun Mitani. Design - Issey Miyake. The project comes from the intersection of creativity and mathematics, resulting in clothing that can be folded flat and become 3D shapes, starting from a single piece of cloth. The IN-EI ISSEY MIYAKE lighting collection was co-developed and manufactured by Artemide. It is a collection of free-standing, table and hanging lights. Each lampshade is created using 2 or 3D mathematic principals, where light and shade harmoniously alternate. Miyake’s unique folding technology creates both statuesque forms as well as sufficient solidity. The structure of the recycled material, together with an additional surface treatment allows these shades to perfectly keep their shape without the need for internal frame, and to be re-shaped when needed. They can be easily stored flat when not in use.
