Someone got the "Kaito" (Japanese male) and "Miku Hatsune" (Japanese female) Vocaloids and
programmed them to sing the theme to Higurashi no Naku Koro Ni together. Cutest anthropomorphized text-to-speech couple ever!
(
Translated version with big distracting subtitles. Not like you'd be able to understand what they were singing even if you know Japanese.)
Now all the world needs is a Broadway musical tragedy featuring American hospital orderlies
Microsoft Sam and
Microsoft Anna. If it's good enough, we can get blind people to cry whenever they use Windows. ^_^
