Amazing engineering here, but isn't this equivalent to raising your camera above the wall and then snapping a pic? This wasn't really seeing behind walls in the sense I expected.
The idea of a camera that can design its own lens by shifting the sensor in a large area is interesting on its own, but the 'hook' is it can "see behind things" by being so large.
The title appeals to a broader audience, and technically it's true, if comparing to any typical camera or working human eyeball arrangement.
It's a bit different than that since the image perspective is as if the camera is directly in front of the wall. Normally if you take a picture from above the wall, the perspective is from the angle of the camera pointing over the shoulder of the wall.
