[Blindmath] hydraulic full screen braille display

[qubit]

The following link was the topic of discussion on the sci-tech list a while 
back. If you want to know more, such as if/when it will be productized, ask 
Sina Bahram.
I wonder if this could do both braille and graphics.  The technology is 
coming, if people demand it.
