Street art is a very specific field of art. We can find it in public locations, in other words, on the street. It's more than a simple graffiti which is an act of vandalism. Street artists create art in public spaces because they want to gain attention of bigger public. This kind of art can be called sometimes : "urban art", "guerrilla art", "post-graffiti" or "neo-graffiti". Lot of artists have their own style and their work is known on the street. There are even several festivals of street art. I think that this is fantastic. Some of these paintings are beautiful and creative. They bring some colours to the gloomy streets of big cities.
