I understand the article and it makes sense.  What I do not understand is how they can make a game for an iPod which requires 2 eyes to play.  Sounds good in theory, but wouldn't my one good eye just do all of the work?  I just don't see how my good eye will miss some of the image that only my right eye is suppose to see... all on one screen?  I'm very skeptical about this and maybe that's why the game has not been published or shared with the public.
