A half-pound drone bought at Best Buy and $20 of hardware put together by a team of University of Waterloo researchers has proven to have Superman-like powers.
Nicknamed Wi-Peep, the device can “see” through walls, surreptitiously identifying the locations of smart watches, phones, laptops and the like, with speed and accuracy.
I think thy already have “x-ray” tech that looks through walls but it is after you not your iPad.
