The mural depicts several geometric shapes - a circle, a triangle, a rectangle, a pentagon and a nonagon and a series of engravings. In order, these are: Three figures, a wave of water, four pyramids, the moon, five flowers and nine towers. It appears to be a riddle of some sort.

Analysis: Additional Information

The icons - figures, pyramids, moon - are too far apart in sense to have any meaning. You think you should concentrate on their order and on the number of objects in each group. This must have some correlation with a geometric shape.

Touch the circle.

Touch the triangle.

Touch the rectangle.

Touch the pentagon.

Touch the nonagon.

Or you can hope that the water is just an illusion.
