My favorite new recursive acronym has to be YOPY = Your Own Personal YOPY. It's recursive on the last letter. Of course, recursive acronyms with this rarer configuration require that the first and last letters be the same.

I notice that many of the recursive acronyms in the open source / free software department contain in their core the letters "IN" for the "Is Not", as in PINE Is Not Elm.

Of course some of these were not deliberate, such as the Amiga emulator, UAE, which was originally "Unusable Amiga Emulator" becuase of it's unstable nature, but then it got stable and was called Unix Amiga Emulator; but after being ported to windows and other OS's it was longer is confined only to UNIX, so many now call it the Universal Amiga Emulator, or for those who prefer a recursive form, simply the UAE Amiga Emulator.
