Street art is related to graffiti art in that it is created in public locations. However, as opposed to graffiti, it is usually sanctioned by the building or landowners.
Where modern-day graffiti revolves around ‘tagging’ and text-based subject matter, street art is far more open. There are no rules in street art, so anything goes. Common materials and techniques include fly-posting (also known as wheat-pasting), stenciling, stickers, freehand drawing, projecting videos, and lighting installations.
Street artists will often work in studios, hold gallery exhibitions or work in other creative areas. Mural painting and the creation of installations give them another venue in which to work.
