Your 3DS Mii is pathetically teensy now, suitable for posing next to hamsters and soda cans. But you could make your virtual self much more (virtually) substantial with the giant AR Card, available now from North America's Club Nintendo for 200 Coins. The 28.5" tall card has the question-mark block on one side, and Mario on the other, allowing it to be used for AR Mario images as well.
Two other prizes were added to the lineup today: for ten coins, you can get a Metroid: Other M screensaver -- released almost a year after the game ... or for 400 Coins, there's a set of three Donkey Kong posters, in the same style as previous Mario and Zelda posters.
