TATTOOS FOR THE BLIND - A SLIGHTLY BETTER IDEA THAN TATTOOS BY THE BLIND:

As if being blind isn’t already way cool enough, an art student in Berlin has created the world’s first Braille Tattoo, a piece of surgical steel, titanium or medical plastic which can be implanted under your skin and read via touch. Inventor Klara Jirkova envisions the first Braille Tattoos placed in the piece of skin between the thumb and first finger, so that when people shake your hand they can read your names and and find out how hip you are.
