They look like this California Quail, quailizing a deer fence on a vineyard. Graffiti artists treat the inorganic streets organically in the same way to humanize it. This conception of the use of space is considered criminal, for the reason that if such behaviour were to continue, the state would lose control of its citizens and a foment of organic organization would rule. To the state, this is called anarchy. To refugees, the homeless, the stateless, those in exile, the roma, jews in Hungary even today, and reservation “Indians” of all kinds (among many others), this is called life.
You can’t paint over it, because it is everywhere.
