We've seen a couple examples of fiber optic fashion. The tops shown here are made by LumiGram and they use fiber optic fabric to illuminate at night. I'm sure these will hit the rave scene in no time at all.
Implications - The shirts function through the use of plastic optical fibers that are woven alongside synthetic fibers. The resulting fabric can be sewn and hand washed as normal, but also has the remarkable ability to light up in a brilliant display. The electronic module component of the fabric can be fueled either by batteries or a small transformer. This is definitely some seriously exciting fashion, so let's hope it becomes increasingly popular in years to come.
