Augmented Reality on DSi?

If you thought augmented reality was restricted to the 3DS, then you must have forgotten about the ‘front’ camera on the DSi/XL, because the way that AR works has nothing to do with the 3D capabilities of the 3DS, it works with any camera and the right software. An example of a use previous to the 3DS was a promotional thing by Cheestrings in which you had ‘Top Trumps’ cards inside of certain multipacks and some of those cards featured the back sillouette image that, with the 3D Top Trumps software, you would be treated to a special animation.
