Nintendo walks us through all of the many apps built into the 3DS. This is what you get out of the box for free the day you buy the system.

We already knew about the ability to take amazing, 3D photos and look at them live. But that's not all you get when you pick up the system. This video walks us through the ability to morph pictures, Mii creation, the info-sharing StreetPass, what the 3DS' shoulder lights do, note taking, friend tracking and alternative reality games.

Stay tuned to Kotaku's 3DS page for a day full of updates, interviews and videos.
