More Ciphers!

Lisa showed us how to make a simple substitution cipher, in which one lettter has a corresponding letter to make a key for deciphering a phrase, like the one below the cipher wheel.

Here is BenFranklin's cipher he used while ambassador to France.  He used a French text to tie the letters to for translating the message.


Here is a grid code.

And here is a simple method of wrapping paper around an item and writing the code across the paper.  When unrolled it is unable to be read, and can only be read when wrapped around a cylinder of appropriate width.
