Damn I hope thats still around. If it is its probably improved as you said. It definitely would be very expensive lol, though I'd love to see if I could find one somewhere. I recall some figure though that braille displays are like 40 dollars a cell, I'm assuming in USD but anywhere thats a lot. This is from Bristol braille did you say? Do you remember what the device itself was called? I wanna google
