One idea is to just have a thin contrasting color overlay for Braille
paper so that when it is punched out the Braille comes through
The other is to plan the paper so that when is interrupted by
Braille printers the failure looks visually like the Roman alphabet
this as marketing for the all in one computer game Visual Braille
