At least graffiti has a fighting chance of meaning a little more to people. Graffiti has been used to start revolutions, stop wars and generally is the voice of people who aren't listened to. Graffiti is one of the few tools you have if you have almost nothing. and even if you don't come up with a picture to cure world poverty you can make someone smile while they're having a piss.

Someone famous once said 'It takes two people to make a piece of art. One person to make the art and another person to stop them from destroying it.' Which is a more poetic than saying: 'It takes two people to make a piece of art. One person to make the art and another person to come round later from the council and sand-blast it off.

There's a famous story about a hobo who hitch-hiked the freight trains across the Australian outback many years ago. He marked his trips by writing the word 'Eternity' everywhere he could in elaborate chalk handwriting. He wrote on so many train cars, bridges and pavements that all across Australia he became part of urban folklore. In 1999 Sydney led the world celebrations for the arrival of a new millennium, and as the eyes of the world watch a spectacular firework display lit up the harbour, at its very center, spanning the length of its famous bridge was the word 'Eternity', spelt out in that same elaborate script by a thousand tiny lights. Fucking sell out." [lightly edited for grammar]

[Letter received to the Banksy website:] "I don't know who you are or how many of you there are but i am writing to ask you to stop painting your things where we live. In particular XXXXXX road in Hackney. My brother and me were born here and have lived here all our lives but these days so many yuppies and students are moving here neither of us can afford to buy a house where we grew up anymore. Your graffities are undoubtably part of what makes these wankers think our area is cool. You're obviously not from round here and after you've driven up the house prices you'll probably just move on. Do us all a favour and go do your stuff somewhere else like Brixton. -daniel" [sic; name and address not withheld]
