CDUV as the most appropriate name for the modern graffiti-plus movement.

Both the pigeon; more formally coined rock dove, and contemporary unsanctioned “street arts” are looked upon with condescending eyes, seen as inelegant despite often having stunningly impressive features. Both spring up sporadically across the urban sprawl making utilitarian use of the chaotic ruin and geometric order alike.
Furthermore, just as a pigeon language, is the child of all and a bastard to any, street art is all encompassing and all inviting.
