Picasso is still influencing me. Of course, I haven't got that kind of energy, or skill.

People from the village come up and tease me: 'We hear you've started drawing on your telephone.' And I tell them, 'Well, no, actually, it's just that occasionally I speak on my sketch pad,'

I'm convinced that technology and art go together - and always have, for centuries.

Cubism was an attack on the perspective that had been known and used for 500 years. It was the first big, big change. It confused people: they said, 'Things don't look like that!'

You can't name the inventor of the camera. The 19th-century invention was chemical: the fixative.

I haven't stopped painting or drawing - I've just added another medium.

There is nothing wrong with photography, if you don't mind the perspective of a paralysed Cyclops.
