Artists may also appreciate the challenges and risks that are associated with installing illicit artwork in public places. Some artists may use "smart vandalism" as a way to raise awareness of social and political issues, whereas other artists use urban space as an opportunity to display personal artwork. The work has moved from the beginnings of graffiti and vandalism to new modes where artists work to bring messages, or just beauty, to an audience. Many instances come in the form of guerrilla art, which is intended to make a personal statement about the society that the artist lives within. Street art is a form of artwork that is displayed in public on surrounding buildings, on streets, trains and other publicly viewed surfaces. Germany's Berlin Wall (shown 1986) was a target of artists during its existence (1961–1989) However, it remains different from traditional art exposed in public spaces by its explicit use of said space in the conception phase.

The issue of permission has also come at the heart of street art, as graffiti is usually done illegally, whereas street art can nowadays be the product of an agreement or even sometimes a commission. Street art is often meant to provoke thought rather than rejection among the general audience through making its purpose more evident than that of graffiti. Street art has evolved from the early forms of defiant graffiti into a more commercial form of art, as one of the main differences now lies with the messaging. It has been associated with the terms "independent art", "post-graffiti", "neo-graffiti" and guerrilla art. Street art is visual art created in public locations for public visibility.
