This is so neat! Per the New York Times (gifted link), "these clothes were produced from yarns laced all over with teensy LED 'balls.' Picture a Times Square billboard packaged into a swaying sack dress. Each design had a battery pack and sensor, allowing the display to be manipulated backstage. (The material is proprietary to Anrealage and was developed with MPLUSPLUS, a Japanese technology design studio.)" Click through and see these pieces in action -- it's so cool to see the images on them twinkle and change. If only someone would wear one of these to Cannes!
