PhotoShop is a program I use all the time with my 2D stuff. And that's an extraordinary program - you really can do anything there, and I've never hit my head on the ceiling. The 3D stuff is incredibly complicated, monstrously complicated, but for the things that I want to do, I've found very simple and interesting ways, I hope, of making images without getting tied up too much in the maps and technicalities.

Sometimes the things I learn making paintings or drawings - composition, colour, expressionism, texture - can directly influence the making of a film. Sometimes it's great that they are different, and simply taking a break from one medium to spend time with another, recharges the batteries and I feel refreshed.

I kind of enjoy the limits. If you've got no limits, you can do absolutely anything, it's very difficult, actually. I always enjoyed working with machines like color photocopiers and letter-pressing type settings, things where the limits are very apparent. You push the machine to do something, and it tries to do its best, and it usually has wonderful qualities all of its own. Then you get a sort of dialogue going, and the limitations become qualities.

Everybody's a bird, locked up in a pretty cage. Sometimes you fly to a slightly bigger one, but you never quite have the courage to abandon captivity completely.

I'm interested in the parallel narrative of our fantasy lives. How the moment of 'now' that is palpably real, is surrounded by our memories, our dreams and hopes, the stories and connections that our brains make as we navigate a universe of fantasy, or unreality, or surreality. I'm keen to explore this very human experience, how our minds create our own realities, a blend of fact and interpretation of fact.

The inspiration is all in the script, in the text. So whatever it is, either it is a film or a book to be illustrated, anything. Everything you need to know is in the text. So the thing is trying to find right tone and voice, the right style, the right way of expressing the emotions in a story or in the location of the story, but it is all in the text.

The filmmakers I really love are the ones that let me look through their eyes for a while. They have an aesthetic and social point of view.
