Not long ago, Nintendo announced a new 3D-enabled version of the Nintendo DS. While details on that upcoming system are still scarce, a new game may suggest how the glasses-free machine will work. A new game called Looksley’s Line Up has you searching for hidden objects in 3D dioramas and will be available this week through Nintendo’s downloadable store. The scenes don’t pop out of the screen but definitely have depth, achieved by overlaying images on the DS’s two screens. Check out the video for a pretty impressive demo.
