I think it would be a pretty simple thing to program. simple problems, puzzles and mini games. appraising the gamer's intelligence level would be as easy as setting up an LJ quiz.
you could even have the face of a bizzare, bespectacled asian man to heckle and praise you. or anything bizzare would work. a puppy with headphones, or a tomato with a face. just so long as its retardedly japanese. hahah.
(I'd be willing to pair up and design this with somebody for the homebrew competition! I can't program, but I'm pretty good in photoshop. I can make the GUI and goofy mascots.)
