You don't need planning permission to build castles in the sky.

I like to think I have the guts to stand up anonymously in a western democracy and call for things no-one else believes in -- like peace and justice and freedom.

I don't know if street art ever really works indoors. If you domesticate an animal, it goes from being wild and free to sterile, fat and sleepy. So maybe the art should stay outside.

I need someone to protect me from all the measures they take in order to protect me.

People say graffiti is ugly, irresponsible and childish… but that's only if it's done properly.

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.

I tell myself I use art to promote dissent, but maybe I am just using dissent to promote my art. I plead not guilty to selling out. But I plead it from a bigger house than I used to live in.

This is a big surprise I don't agree with the concept of award ceremonies, but I'm prepared to make an exception for the ones I'm nominated for. The last time there was a naked man covered in gold paint in my house, it was me.

T.V. has made going to the theatre seem pointless, photography has pretty much killed painting but graffiti has remained gloriously unspoilt by progress.

If you want to say something and have people listen then you have to wear a mask. If you want to be honest then you have to live a lie.

Modern art is a disaster area. Never in the field of human history has so much been used by so many to say so little.

We can't do anything to change the world until capitalism crumbles. In the meantime we should all go shopping to console ourselves.

I wanted to highlight the destruction in Gaza by posting photos on my website -- but on the internet, people only look at pictures of kittens.

You can win the rat race but you're still a rat.

When you go to an art gallery you are simply a tourist looking at the trophy cabinet of a few millionaires.

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.

All artists are willing to suffer for their work. But why are so few prepared to learn to draw?

You live in the city and all the time there are signs telling you what to do and billboards trying to sell you something.

Should graffiti be judged on the same level as modern art? Of course not: It's way more important than that.

All I know about what people think of my gear is what a couple of my friends tell me, and one of them always wants to borrow money, so I'm not sure how reliable he is.
