"The dress is constructed out of individual slide film images that are backed with LED’s. An Arduino Lilypad connected to a light sensor controls the brightness of the LED’s. The sensor reads how much ambient light there is and uses this value to determine if the LED’s will be off or on. When there is lots of light the LED’s are off and it looks like a shiny black dress with small hints that something else is going on. Once the sensor determines there is the right amount of light for LED’s to be seen in their full brightness it turns them on. When the dress is on the lights slowly pulse and the images on the dress come alive."
