Well... not exactly.

The same idea that was used for the Wii way back.

Wii?

That's awesome!

This makes me almost want an iPad...

Even the DSi already had this. It's called head tracking, not glasses-free 3D.

This DSi game will probably be one of the first titles I'll download once the e-shop hits the 3DS.

Hopefully they re-code something or the 3DS camera's are better, because the head tracking doesn't always work (next time I'll play with the device pointing at the ceiling). On the feedback I gave to Nintendo, I said they should rework the game whenever the next handheld comes out to include gyro input, in comes the 3DS.

Ever since I first saw this, I sortof thought that future video games would use this, (even on PS3 and 360, with their respective PSeye and kinect)

But nothing!

When I first heard about the 3DS last year I thought it would be something like this. Yes, I know it's not 3D, but it looks like it.
