Things as simple as an apartment number in shade can be art. The result is more abstract that the usual photograph. The late morning sun casts the shadow across the brick and made just the right pattern. The apartment number stands out of the shadow.
Perhaps this is more about photography than the urban environment. Sometimes, the simple things are the ones to pay attention to. Even if the architect never intended some aspect to be art, you can draw it out with the right view. But you also need a bit of luck and some post-processing.
