Wearable tech: Lunar BLU Jacket

This product isn't really going into retail, sadly, but this concept design does leave a room for imagination.
The BLU Jacket is designed by Lunar Design. It is basically a jacket with electronic paper sown into it, allowing the surfaces to shift into any image or video that you want. The designers thought that it could be used to show the wearers mood and generally be decorative.
In a commercialized world however, this could be used as a human adboard, where the wearer earns a little bonus on the side for wearing it. The possibilities are many, so maybe, just maybe, this is something we are going to see a lot more of in the coming years.
