Roll-Up Braille

In the same vein as an electronic newspaper, a new portable electronic Braille display has been announced, small enough to fit in your pocket—and can even be rolled up. Basically, it's "a sheet of tiny plastic paddles that bend in response to a voltage. It is designed to connect to a cellphone or laptop, and could also replace the liquid crystal screen of an ordinary PDA." This looks to be a huge breakthrough because the only dynamic displays for the blind right now are about the size of a New York phone book.
