Starting on July 13, European Nintendo 3DS owners can download the Nintendo Video application from the eShop.

This program will give users access to both 2D and 3D videos via SpotPass, downloading video automatically when the 3DS is close to a wireless connection. Already announced as content will be 3D episodes of Disney Australia's Oscar's Oasis, 3D Magic Tricks from studio D4D, and a cartoon based on the French books, Angelo.

No word yet on when, if ever, a similar application will be made available for North American 3DS units.
