Electronic cigarettes. The nicotine of the future. The kind of smoking that is not by smoke, but vapor. This battery is a tribute to my e-cig of choice, Blu. The battery part is drained when your iDevice is drained. When the device is charged, the battery part of the e-cig is full, and lights up at the tip. May seem basic, but quite a few hours were put in to this. I may also add a glow effect on the light too, but for now, enjoy. Even distribution of pixels for accuracy, and also in HD!
