another good substitution type would be using a matrix with a known code word and the matrix itself (consisting of a horizontal line of numbers and letters in sequence, and a vertical line on the left side also of in sequence you would use a code word at the top and then point to each letter on the H and V and then go to the letter or number it indicates in the matrix. Mind you, this is a pen/paper type of encrypting that would be hard to break unless you know the code word and know the table layout. Then you can get real crazy by assigning number values to each braille cell (such as A = 1000000, b = 120000 and so on). This would allow you to add a second layer of encryption.
THis may be a bit extravagant when it comes to keeping your passwords safe and usable by you, but it certainly would frustrate someone seeking to breach your machine with physical access.

>> Sadly, Google is the password cracker's best friend. It can teach the person who steals that card with the braille password on it all he or she needs to know about how to read it. Other ways of writing down the password may be used, including mnemonics, but if a mnemonic is written well enough for me to remember a random password, chances are it's also good enough for someone else to use to gain unauthorized access as well. That said, if you can hold the mnemonic you use to remember a random password in your head without writing it down, and if the mnemonic is good enough to allow you to enter the password correctly every time you need it, then a computer generated password is probably best, as the only point at which you need to worry about compromise is the time between its generation and your commitment to memory.
