Braille Info
Braille was invented by Louis Braille who was born in 1809 and lost his sight
when he was 6. Braille gives the blind the ability to read and do mathematics.
Braille consists of a series of raised dots. A braille cell consists of a '3
row x 2 column' grid. Anyone of these 6 dots can be raised to form different
combinations. These combinations are interpreted to mean different characters,
numbers, or groups of characters. There are 2^6 - 1 different possible
symbols. This is only 63, however some braille codes can be used in
combination to form others making the possiblities endless.
Another interesting note is that one of my favorite composers Ray Charles, was
blind at the age of 7.
Why I care (since I'm not blind)
I've always been interested in different ways to represent things. For
example, in my projects section I have a project on steganography (encoding
data into normal images by using pixel color variations). It used to be
something I've always wondered about but had no clue about. So I decided
to learn it. Who knows, maybe I'll be able to develop something in the
future that can help.

Braille Numbers
Braille numbers are actually the same as the letters. Except they have a
special braille code that is used before them to signify that they're a number
instead of a letter. 1 is a, 2 is b, 3 is c, ... , and 0 is j
