[Blindmath] grayscale braille

[Michael Whapples]

I don't know if John is on the blindmath list, I'll forward the message on 
in case he isn't, however it would be better if you could somehow 
communicate direct with him (eg. by posting to the NFB-science list if he 
isn't on blindmath).

Hi John,

Can I use this plotting technique for any image? Your example seems to work
only for functions.
