I am an all-surface wallpaper man that retired to become a printer.

Art is not supposed to change the world, to change practical things, but to change perceptions. Art can change the way we see the world. Art can create an analogy.

Even when I do really big pieces, I do them strips by strips - so you have to paste, you have to involve people. It's a whole process. And I like that. For me, that's where the artwork is.

I want to create the largest-ever participatory art project and highlight the concept of Shadow Philanthropy, where people help others create work without taking credit for it - through this we can really change the world.

If there's one thing I've always taken care of with my work, it's that it's never an advertisement for anything other than the work itself and for the people it's about - no 'Coca-Cola presents.'
