What do you do with a 3DS and free time on your hand in Japan? Make a giant home-made AR card of course! For those unfamiliar with them, AR cards are those little Augmented Reality cards that the 3DS can read and project a 3D model onto.
Some guys have made a huge one, in order to generate a Mii that rivals the size of some manga/anime robot thing I'm glad I don't recognize. All I know is that it isn't a Clan Jade Falcon mech wielding a drill that pierces the heavens (Google tells me it's Tetsujin 28). Still, pretty amazing stuff.
