Babelizer is a toy that humorously exposes the inadequacy of machine translation. You type in a phrase, choose a language, and the Babelizer uses the Altavista translation web site to translate between English and your chosen language until the result no longer mutates.
I speak other languages real good.
Je parle l'autre vrai bon de langages.
I speak other good truth about languages.
Je parle l'autre bonne ri au sujet des langages.
I speak the other good truth about the languages.
Babelizer is free software. It is free as in beer, and it is free as in redistributable with source code, as explained in the license.
