On March 3rd, Japanese Nintendo DSi owner can download the DSiWare game Rittai Kakushi e Attakoreda (立体かくし絵 アッタコレダ). I don’t know what the games about, but I do love the 3D interface. It’s use the middle camera between the two DSi screens to track you eyes and use that information to display the right angel of th content on the screen. Watch the video bellow to see how it works. If you move your eyes or your DSi, the objects in the game moves. Pretty cool.
