The internet has extended the possibility of making art to more people, and particularly of enabling it to be seen by others. I am sure the internet is having a profound impact on art, particularly those who have grown up with it, but making good art will remain as difficult (and as easy) as it ever was. Having a lasting impact may become more not less difficult.

I think that cultural influence is very deep, it is not on the surface and this is true in every culture.

The first exhibition that I used bright colours in painting the room was at a gallery in Paris, and there were seven rooms in the gallery. It was very nice gallery, not very big rooms, around the courtyard, it was a very French space. So I painted each room in different colour. When people came to the exhibition, I saw they came with a smile. Everybody smiles - this is something I never saw in my work before.

There is a complete difference between art and the art market. Prices are high now for the simple reason that there are people are willing to pay them. The market dominates the art world today because at the moment collectors call the shots. Like everything else that won't last forever.

All the basic information should be in the object itself.

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 a sense [Joseph] Albers was an authoritarian teacher. He had rules about most things and very definite ideas.
