Today Apple unveiled the iPad Air 2: a super-thin followup to its super-thin predecessor that packs quite a punch. But, beyond the new A8X chip, faster WiFi/Cellular and TouchID sensor, the most interesting upgrade was actually the camera, which had remained largely unchanged for a solid two years.
NASA mechanical engineer Mark Rober made an uber-creative halloween costume that features a gaping see-through hole in his torso. What he did was strap two iPads to his body — one in front and one in back — with a FaceTime video chat running between them. Each iPad’s camera footage is displayed on the other iPad’s screen, providing a view right through Rober’s body.
