This was a demo released sometime earlier than the announcement. I'm not sure how connected it is to the new 3DS, but it should give a good rough outline of how different this tech will be than traditional 3D that pops out. The device will essentially look into a 3D environment, almost like opening a box and seeing the contents inside. Again, this is just a guess, but I feel this may be somewhat like what we should expect from the 3DS.
