The first 3,000 people to register their 3DS on the Club Nintendo website were awarded a limited edition Augmented Reality T-Shirt. Many 3DS owners will already be aware of this feature as the console came with AR cards that create creatures that pop out and are displayed in 3D as well and can be interacted with in various ways.
So, were you one of the lucky 3,000 owners of this awesome shirt? If not you can always scour Ebay as I am sure there will be a couple owners of it that care more about money than fun.
The shirt may seem sort of odd to those unfamiliar with the 3DSs abilities, but children will certainly get a kick out of it.
