Fiber Optics
I had heard of fiber optics woven into rugs before. However, for some reason people had not posted pictures of these rugs. It is an interesting twist, however, unless used with the utmost care it could be rather ostentatious.
Here is a picture in which the fiber optics in the rug totally seems to fit with the scene (yeah the points of light from the ground are light comeing from the rug).
Here is a link to the designer’s site.
