I, as a street photographer, frequently look down. That’s where the street is, of course. There are also interesting things to see on the sidewalk. My photo below reminds me of a flag. See Flag of an Unknown Country.

I think this is a country I’d like to visit. Their flag is much to my taste!
There are all kinds of flags waiting to be carved from streetscapes.
