So I paid the fee and walked up the tallest building in town, the Firetower. The street down there had been completely empty for a long while, and I found myself concentrating on the different colors and textures of the cobblestones, which had looked to me all the same in the beginning, but then each of them looked as if having its own identity, and nobody came, so I began discovering some interesting regularity in the geometric patterns down there, and not some chaotic distribution, and finally this guy with that hat showed up.
(I include the original vertical format in the "workshop", actually it was hard to choose...)
