Fallout graffiti

Graffiti are writing or drawings scribbled, scratched, or sprayed on a wall or other surface in a public place. Graffiti ranges from simple written words to elaborate wall paintings. The collapse of society and law allowed graffiti to enjoy a renaissance, becoming truly ubiquitous.

In the Fallout series, graffiti can give clues to the locations of important items, be developer in-jokes, allusions to pop culture or be clues to future DLC; other times it may just be meaningless.
