Tangentially related, but I built a Chrome/Firefox extension a while back that converts random words on a webpage as you browse into braille, ASL, Kana, etc.

So if you're ever interested in practicing Grade I Braille in the most functionally useless fashion (by reading it visually) feel free to check it out.

It's also completely open-source.
