What your seeing is a set of windows which as you noticed is covered by plastic wrappers.
The story goes back around a month ago. Our Mapeh teacher and for the rest of Grade-9 sections gave all of us the same project, Cover the windows with culture in a mosaic style.
As you can see this classroom and all of the students decided to take Roman-Catholic as their culture for their mosaic. In all honesty they did a well splendid job assembling/creating all the pieces for this master-piece. Although their interpretation is misleading, if your a Roman-catholic you should know that there should only be 13-beads in the object their trying to represent.
For the A.D.I.B part i have no clue. But overall they got high-grades!
