A bronze-colored sheet metal stamped into a pattern of pentagons, forming the “Cairo tiling”, adhered to a wall. The pattern appears to be textured, with each pentagon's apex closest to the wall, sloping outward to its base, where it joins the base of the adjoining pentagon.

Farther-back view of the same wall decoration, showing where it meets the ceiling, and where the well ends. Red and white lights can be seen reflected in the pentagons.
