It makes me embarrassed to pass in front of my eyes, a little troubled wall

A picture of a wall with a slight design problem. There is a hole like a leaf of clover on the lower side of the ordinary wall, it is a wall without seemingly hints too, but when sunlight is inserted from a certain angle, a form that seems to have something to appear appears.

Let's see why the walls that have not seen anything and no hints are at issue.

Pictures are as follows.

This is the wall of the problem. By inserting sunlight from the wall side, it looks like something lined up on the road.

I took out one.

Let's dare not let it go further.
