We all saw the Shield Pose, Chase Mii, Battle Mii and Zelda HD Experience Wii U demos from E3, but one we didn't get to see was Panorama View, recently shown off at CES.
The 360º video experience shown below is unlike anything Nintendo showed off before. Using the Wii U controller you can look around the space as you like, even looking at the road below the car. Quite how this is possible we don't know: our best guess is magic.
Still, it's a mighty impressive technology demo all the same.
