Film is incredibly democratic and accessible, it's probably the best option if you actually want to change the world, not just re-decorate it.

I'd been painting rats for three years before someone said 'that's clever it's an anagram of art' and I had to pretend I'd known that all along.

Gaza is often described as 'the world's largest open air prison' because no-one is allowed to enter or leave. But that seems a bit unfair to prisons - they don’t have their electricity and drinking water cut off randomly almost every day.

All graffiti is low-level dissent, but stencils have an extra history. They've been used to start revolutions and to stop wars

I used to encourage everyone I knew to make art; I don't do that so much anymore.

Traditional graffiti writers have a bunch of rules they like to stick to, and good luck to them, but I didn't become a graffiti artist so I could have somebody else tell me what to do. If you're the type who gets sentimental about people scribbling over your stuff, I suggest graffiti is probably not the right hobby for you.

I don't think you should have to pay to look at graffiti. You should only pay if you want to get rid of it.
