[bfxwmorg] Ringtone theme and variations

Choose a "theme" ringtone for your phone.  For every caller, the phone synthesizes a unique variation on the theme using the caller's identity (caller ID, or directory entry) as the seed for a random number generator, similar enough to the theme to recognize it as your phone, but different enough that you can learn to discern caller identities by sound without having to look at the display.
