"Graffiti is revolutionary, in my opinion", he says, "and any revolution might be considered a crime. People who are oppressed or suppressed need an outlet, so they write on walls—it's free."
In Australia, art historians have judged some local graffiti of sufficient creative merit to rank them firmly within visual art. Oxford University Press's art history text Australian Painting 1788-2000 concludes with a long discussion of graffiti's key place within contemporary visual culture, including the work of several Australian practitioners.
Artistic graffiti is a modern day offspring of traditional graffiti that has elevated itself from just scrawling words or phrases on a wall, to a complex artistic form of personal expression.
Between March and April 2009, 150 artists exhibited 300 pieces of graffiti at the Grand Palais in Paris — a clear acceptance of the art form into the French art world.
