Here are some examples of RecursiveAcronyms:
- GNU - Gnu's Not Unix
- Pine - Pine Is Not Elm
- MINCE - MINCE is not complete EMACS
- PHP - PhpLanguage (after going through some name changes)
- TheGimp - once was 'The Gimp Image Manipulation Program' but now is 'The GNU Image Manipulation Program'. So the GnuProject doesn't only create a lot of RecursiveAcronyms, some are also destroyed because of it.
Pine is actually "program for internet news & email". See http://www.washington.edu/pine/
The GnuHurd probably is the first software to be named by a pair of mutually RecursiveAcronyms:
- Hurd - HirdOfUnixReplacingDaemons
- Hird - HurdOfInterfacesRepresentingDepth
