Did you know you could use Nintendo's 3DS to do augmented reality on an iPhone? No, no. Not using an iPhone. I mean on top of an iPhone.
Totilo forgot to bring his AR Cards into the office today, so instead of printing some new ones, we just copied them onto our phone. Not only did they work perfectly, the light from the phone actually made it possible to use the augmented reality modes in rooms without as much light.
Worried you might forget your AR cards after you get your 3DS? Worry no more. Just put them on your phone!
