Looks really nice, and the cable looks awesome as well.
Quote from the site:
The Lightning Cable has an intelligent power managements system built in, you can actually see the flow of current going into your iPhone 5. When the light flows, it tells you your device is charging. When your phones fully charged the cable illumination turns off. The illuminated Lightning Cable uses electroluminescent (EL) technology to display the current flow from the power source to your device. The current flow speed is dependent on how flat your device is. The lower your battery the faster the current flows. Once nearly charged the Illuminated EL strip slows right down before stopping and turning off.
