Pace yourself and repeat [graffitiing] as often as you feel inadequate and no-one listens to a word you say. - Banksy

Recipe idea: take on fire extinguisher and pour out all the contents. Mix down a nice bright emulsion paint to the consistency of full fat milk, stirring constantly to remove any lumps. Pour into the extinguisher, screw on cap tightly and write on things up to 50 feet high. Re-use by swapping over the CO2 charged canister (costs about one pound). The perfect accompaniment to a night out drinking heavily with friends.

Well I'm frustrated by many things but trying to get accepted by the art world isn't one of them. This seems difficult for some people to understand - you do not paint graffiti in the vain hope that one day some big fat tory will discover you and put your pictures on his wall. If you draw on walls in public then you are already operating on a higher level.

The problem with painting in Zoos is that it's slightly too effective. They tend to get rid of it as soon as possible. I'd had enough when the rope ladder into the Chimpanzee enclosure at the Sydney Zoo snapped and I fell into the moat getting a mouthful of monkey piss. By 10am the next morning the words 'Please help me get out of here I am the victim of a cruel scientific experiment... I am not a monkey... Somebody do something' had been completely painted over. The solution was to write stuff on cardboard and throw it into the enclosures when no one was looking. Then you just sit back and listen to the explanation parents give as their kids ask 'Why don't we just let them go home if they want to, mummy?'
