I hadn't heard of diffraction grating but it sounds like they can steer light by having it travel through layers of changing air density resulting in a kind of air lens. That's rad.
These applications aren't really relatable but I imagine lensless lenses have a bunch of applications.

For the first time ever?
So every time flat earthers take a laser out over water and prove that the earth is flat, but globe earthers say "no, no, no, it's diffraction through different layers of air density that causes a laser to follow the curve of the earth" the flat earthers were actually correct?
