What would happen if all graffiti writers overnight would write their name backwards? It is a cheap paperback cliche of occultism that reading the bible backwards will undo the universe while the devil supposedly can be heard by playing certain records backwards. It is enough to mention Babylon, that ancient dystopia of linguistic diversion, to remind you that messing with the structure of language has always been considered to be dangerous. It is the power of computers to generate all permutations that can made by combining according to different rules a certain range of tokens. It would not be hard to code a small software running on your pocket PC or Mobile phone that would tell you what combinations could be made with words you encounter while out on your game: the man-machine graffiti interface.
