The only art
Graffitists are the only PURE visual artists in today's world. Commercial art, animation, movie FX, etc, are wildly active and wildly creative, but don't quite count as pure art.
The people who call themselves Artists, the sadistic brutes who get exhibited in museums and discussed in Art Classes, have been pulling cruel hoaxes since 1910, and can be utterly dismissed. Elephant shit.
If you want Realism, Impressionism, Trompe l'oeil, Mosaic, or any of the classical styles that should be called visual art, you want graffiti. Nothing else.
This piece in Detroit (photographed by 'Tooloose-LeTrek') isn't among the best in technique, but it expresses the whole universe in an elegant symbolic narrative. It's the painterly equivalent of Euler's e^i*pi+1 = 0.
