How does Ivan describe a little bit of the world that he can see?

From the text:

A jungle scene is painted on one of my domain walls. It has a waterfall without water and flowers without scent and trees without roots. I didn’t paint it, but I enjoy the way the shapes flow across my wall, even if it isn’t much of a jungle.

I am lucky my domain has three windowed walls. I can see the whole mall and a bit of the world beyond: the frantic pinball machines, the pink billows of cotton candy, the vast and treeless parking lot.

Beyond the lot is a freeway where cars stampede without end. A giant sign at its edge beckons them to stop and rest like gazelles at a watering hole.
