Cryptoquotes are puzzles with letters. One letter substitutes for another so it looks like mish mosh and you have to decipher it to see the famous quote.

For example, AQ IMJFQA XF KQZJ PJXMAG VSQ GMCWAGF KQZJ FXOMABM, QJ GMAXMF KQZJ JXTSU UQ TJQV. – WOXBM VWODMJ

When it is resolved it is: No person is your friend who demands your silence, or denies your right to grow. – Alice Walker

This is the sort of puzzle that makes words out of letters and patterns. I have collected years of these. Many times I will start my blog with a quote and then just riff. This brings me great pleasure. Both the solving and the sharing and the writing about it.
