Totally clickbait the idea of testing out different lenses is great but in order to see behind the wall he just puts the camera higher around the wall and then makes the picture. I was personally expecting a breakthrough or a mechanism that is smaller and doesn't go above the object in order to make a picture from the simulated lenses.
