I observed and that was my conclusion not baseless assumption. Try using just shapes of different colors. Same test. Cycle through. I would theorize that the shapes would appear to merge into deformities as well. I doubt any type of magics or super phenomenon is present other than the rantings of demons and aliens and shit. Like apes discovering a weird pillar that shows up and they become agitated and are confused. Hit it. Throw poo at it. Because they don’t understand it.
