Chinese company Chocolate Agency is working on a concept e-paper slap bracelet. The accessory is made of a thin, flexible, high contrast screen that can display images. In addition, the length of the bracelet can be altered simply by adding magnetically attached extenders. This concept bracelet is powered by the body's natural movement.
E-paper technology is still at its conceptual stages but the possibilities for it to enhance existing personal technology such as MP4's, watches, GPS etc are seemingly endless.
