    hemm…it might be an optical illusion with each scratch acting like a curving lense to diffuse the light circularly.

    I will and it’s surprise to see order (circular pattern) in the chaos (random sctraches).

    not sure, but try searching for diffusion of light…
    if you look at a light source through a cloth.. you again get the same result
