Today, in British education, we don't have that kind of freedom. Now there are many regulations, many rules, and bureaucracies in the education system. So, it doesn't have the flexibility that it had in the '60s, '70s, '80s.

As an artist you are free to use any image, any style, any idea from any culture and any period of history.

Sometimes we look at a work of art and we immediately think that it is German art, but with some we don't, it's not so obvious.

I had been doing wall drawings, but they were always black and white. Then in 1993 I painted all the walls of a room to make an installation and as soon as I saw the colour on the walls, it changed my whole life.

In my early work I didn't use much colour. I had no confidence about how I could do this.

You can't honour someone by copying them or trying to be exactly like them.

When I look at the objects that I draw, it seems to me so obvious about the contemporary world - these are our world.
