    Nature[^]:

    Digital cameras have been used to reconstruct rough images of hidden objects just by analysing light that bounces off a wall.

    Or you could ... you know, go around the corner?

      They'll get no attention at all, because they didn't mention AI.

        Some years ago, it was a specialized camera.[^]

          We use mirrors for that; very low electricity-usage and real-time feedback.

            ...or a mirror?

            - I would love to change the world, but they won’t give me the source code.

                  Hmmmm. You've just given me some food for thought. From memory, lasers that are above a certain limit of power can do funky things to the air they travel in. Wonder if you could aim a stupid powerful one at a mirror and have the altered air damage the surface, at which point you could reduce power and go-for-gold. Yep, looks like a winner - Laser-induced breakdown spectroscopy seems to rely on the phenomenon I was thinking of - namely the ability to create a super-heated plasma from the air by laser-pumping. Hitting the surface of a laptop-drive with an HV source (think taser) is fun. It leaves the surface rough to the touch since the glass fractures from the tremendous localised heat.
