I wanted to learn to write Braille, and I figured the most useful thing to do was to implement a Braille writer java applet. That way other people could also use it to learn how to write Braille.
I actually started it the other day, but got distracted by other things. So today I finished it up, and I’ve put it on-line at http://kenperlin.com/braillewriter.
Seems like one of those things that should have already been out there somewhere as a free resource. Better late than never.
