Infosthetics posted this post originally. The Videos show a variety of dresses by the designer Hussein Chalayan. There are two major themes with these dresses. One is the color changing, video screen dress. The dress is made with LED's sewn into the fabric, most likely this is Phillip's Lumalive fabric. The second theme is shape changing (and occasionally disappearing), dresses (wait until the end of the video). These are pretty neat, too. According to infosthetics, the dresses are powered by many small motors and a hidden battery pack.
