Hi Thibaut,

I have this rufus-mnemo that turns integers into "user friendly" strings.

http://github.com/jmettraux/rufus-mnemo


After a "sudo gem install rufus-mnemo"

you can do things like

---8<---
require 'rubygems'
require 'rufus/mnemo'

s = Rufus::Mnemo::from_integer(125704)

puts s
      # => 'karasu'
--->8---

Not exactly what you want, but could be funny. It's using a restricted
syllabary (the Japanese one) to turn integers into words (and back).

As twittered, it has the potential to generate insulting words. The
generated syllables sequences are quite easy to the latin ears though.


Best regards, meilleurs voeux pour 2009,
