This is the final product of my device to show how the "imperfections" vanishes
into the shadowy luminous breadth. I can see things in front through the
transparency sheet (left picture). If I do not wish to see certain things (the "imperfections") that are in front of me, I can open the mirrors that's on the side and see things behind me instead (making "imperfections" disappear).
However, there's a small gap in the middle of the four mirrors. It is to show that even if I can "make imperfections vanish", it wouldn't disappear completely, but only "entering" in small amount.
