Imagine a city where graffiti wasn't illegal, a city where everybody could draw whatever they liked. Where every street was awash with a million colours and little phrases. Where standing at a bus stop was never boring. A city that felt like a party where everyone was invited, not just the estate agents and barons of big business. Imagine a city like that and stop leaning against the wall - it's wet.

I’ve learnt from experience that a painting isn’t finished when you put down your brush – that’s when it starts. The public reaction is what supplies meaning and value. Art comes alive in the arguments you have about it.

I've never really understood why people sleep. Wasting a third of your life and becoming vulnerable for almost 8 hours every night. Doesn't seem very appealing to me.

Fight the fighters, not their wars.
