This is a really nice wearable LED dress designed & prototyped by Cutecircuit in the UK. Really impressive work. According to Ecouterre there are 24,000 LEDs that each measure 2×2 millimeters. Add 4 layers of silk and a few thousand Swarovski crystals and you’ve got something really gorgeous. If you want to see it in person, it is on permanant display at the Museum of Science & Industry in Chicago.
