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

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

I just wanna make the world a better-looking place. If you don't like it, you can paint over it!

But there's no way round it-commercial success is a mark of failure for a graffiti artist. We're not supposed to be embraced in that way. When you look at how society rewards so many of the wrong people, it's hard not to view financial reimbursement as a badge of self-serving mediocrity.

If you don't own a train company then you go and paint on one instead... it all comes from that thing at school when you had to have name tags in the back of something... that makes it belong to you. You can own half the city by scribbling your name over it.

I wouldnt want to be remembered as the guy who contaminated a perfectly legitimate form of protest art with money and celebrities.

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