This bracelet looks like something that Marty McFly would give his girl in the Back To The Future movies. They have taken an outdated fashion from the 80’s, and turned it into something pretty cool. These E-Paper Slap Bracelets are powered by kinetic energy and display photos without needing a recharge.

Chocolate Agency has come up with this multimedia device that snaps on with a slap. The entire surface is E-Paper and so is thin, high contrast, and power efficient. You can adjust the length by adding magnetic snaps to the ends. Now, if you just had a hover board and a Delorean, you would be all set.

For the moment, it’s a concept, but something tells me it won’t be long until we see this in the wild.
