Graffiti is one of the most popular activities of modern street youth, especially the members of juvenile street gangs. It is a special form of street art (so called
wall art), which includes any sort of drawings, images or simple inscriptions, created by amateur artists on the walls or other elements of the interior or exterior of various public places. In our times, street artists use quite advanced techniques and tools far beyond usual good-old aerosols. Also, more and more of new graffiti types and styles have been emerging recently.
