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

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.

Remember crime against property is not real crime. People look at an oil painting and admire the use of brushstrokes to convey meaning. People look at a graffiti painting and admire the use of a drainpipe to gain access.

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

People are fond of using military terms to describe what they do. We call it bombing when we go out painting, when of course it's more like entertaining the troops in a neutral zone, during peacetime in a country without an army.

I mean, they say you die twice. One time when you stop breathing and a second time, a bit later on, when somebody says your name for the last time.

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.
