are visible, tiled, clean and cool blue, you can see the extents of this space. Above you, sunlight glistens and twinkles in refracted arcs. There are seats, places to rest, anchored to the walls within easy reach. The floor is soft and dark blue, and as you look down your air bubbles pass your face in
streams of glittering rounded shapes. You feel comfortable here.
