I wonder if the next generation of braille will be not just this, but in the smartphone with a taptic engine like that in the iPhone. I can imagine that the engine becomes sensitive enough to deliver minute changes as the user runs their finger across... In any case, it's really cool that things like this exist, because it makes being blind a little bit less bad; instead of a $15,000 printer, you can buy this ink for much cheaper.
