Have a look at this awesome Indiegogo project for E-Ink shoes. Creators, Volvorii, designed the shoes with a e-ink display and a Bluetooth so that you can use your smartphone to change the pattern whenever you want. You will notice that there are even snaps on the front and on the back that allow you to customize the shoe even more. If you act fast and make a pledge at the $249 level, lowest level left you can get yourself a pair just in time for Christmas.
