The Chocolate Agency, which sadly has absolutely nothing to do with delicious cocoa, has designed the conceptual E-Paper Slap Bracelet. It's an MP4 player in which the entire surface acts as a thin, high contrast and energy efficient screen. As an added bonus it needs no charging -- it's powered by the kinetic energy produced by moving your arm. Say, did you know when slap bracelets first came out they were just a piece of rusty metal covered in plastic or cloth? Yeah, me neither, well at least not until the lockjaw set in.
Another conceptual picture after the jump.
Thanks to Melissa, who is not conceptual but rather a real-life, beautiful woman, for the tip
