Transmaterial wrote about Delight Cloth - it is a light-emitting textile comprised of thousands of fiber optic strands. With a diameter of only 0.25 to 0.5 mm, the optical fibers are woven into a large translucent tapestry that can be hung vertically or horizontally. The material may be used for wall or ceiling treatments, as well as banner signage or clothing. Delight Cloth can be fabricated with imbedded graphics or logos, and may be used to emit a wide variety of colors of light. Contact: Lumen Co., Ltd., Tokyo, Japan.
