I love Braille writing.  I love the fact that it is non-visual language, and the fact that my work is useless to a group of human beings like myself, who can't see, reminds me of how limited the visual world can be.
I have a Braille Typing machine, and I know how to read and write Braille both in English and in Hebrew, Alas' the tup of my fingers is not sensitive ebough to recognize the letters.
