Free Return from the Stars by Stanislaw Lem

begun to annoy me. And after a single day! Odd that they liked it. Strange tastes. But then I recalled the view of the Terminal at night,
    I needed to get myself some clothes. With that decision I stepped out into the street. The sky was overcast, but the clouds were bright, high up, and the sun shone through them occasionally. Only now did I see—from the boulevard, down the center of which ran a double line of huge palms with leaves as pink as tongues—a panorama of the city. The buildings stood like islands, set apart, and here and there a spire soared to the heavens, a frozen jet of some liquid material, its height incredible. They were no doubt measured in whole kilometers. I knew—someone had told me back on Luna—that no one built them any more and that the rush to construct tall buildings had died a natural death soon after these had been put up. They were monuments to a particular architectural epoch, since, apart from their immensity, offset only by their slimness of form, there was nothing in them to appeal to the eye. They looked like pipes, brown and gold, black and white, transversely striped, or silver, serving to support or trap the clouds, and the landing pads that jutted out from them against the sky, hanging in the air on tubular supports, were reminiscent of bookshelves.
    Much more attractive were the new buildings, without windows, so that all their walls could be decorated. The entire city took on the appearance of a gigantic art exhibit, a showcase for masters of color and form. I cannot say that I liked everything that adorned those twenty- and thirty-floor heights, but for a hundred-and-fifty-year-old character I was not, I dare say, overly stuffy. To my mind the most attractive were the buildings divided in half by gardens. Maybe they were not houses—the fact that the structures were cut in the middle and seemed to rest on cushions of air (the walls of those high-level gardens being of glass) gave an impression of lightness; at the same time pleasantly irregular belts of ruffled green cut across the edifices.
    On the boulevards, along those lines of fleshlike palms, which I definitely did not like, flowed two rivers of black automobiles. I knew now that they were called gleeders. Above the buildings flew other machines, though not helicopters or planes; they looked like pencils sharpened at both ends.
    On the walkways were a few people, but not as many as there had been in the city a hundred years earlier. There had been a marked easing of traffic, pedestrian especially, perhaps because of the multiplication of levels, for beneath the city that I had seen spread successive, lower, subterranean tiers, with streets, squares, stores—a corner infor told me, for example, that it was best to shop at the Serean level. It was a first-rate infor, or maybe by now I was expressing myself better, because it gave me a little plastic book with four fold-outs, maps of the city's transit system. When I wanted to go somewhere, I touched the silver-printed name—street, level, square—and instantly on the map a circuit of all the necessary connections lit up. I could also travel by gleeder. Or by rast. Or—finally—on foot; therefore, four maps. But I realized now that traveling on foot (even with the moving walkways and escalators) often took many hours.
    Serean, unless I was mistaken, was the third level. And again the city astounded me: coming out of the tunnel, I found myself not underground but on a street beneath the open sky, in the full light of the sun; in the center of a square grew great pines, farther off the striped spires took on a blue tint, and, in the other direction, behind a small pool in which children were splashing, riding the water with colorful little bikes, there stood a white skyscraper, cut by palm-green bands and with a most peculiar caplike structure, shining like glass, on its summit. I regretted that there was no one I could ask about this curiosity; then suddenly I
