Your rainbow panorama enters into a dialogue with the existing architecture and reinforces what is assured beforehand, that is to say the view of the city. I have created a space which virtually erases the boundaries between inside and outside – where people become a little uncertain as to whether they have stepped into a work or into a part of the museum. This uncertainty is important to me, as it encourages people to think and sense beyond the limits within which they are accustomed to moving.

Artists are valuable to public discussion: They show the correlation between doing and thinking.

I am not opposed to the art market. I have lots of friends who are collectors. But the whole idea of the art market is complex. Sadly we have a situation where auction houses and secondary market dealers are creating a lot of confusion and unnecessary pollution.

I myself have already spent a third of my life in Germany, first in Cologne and then, since 1994, in Berlin.

By bringing Little Sun to Tate Modern and the London Olympics, I hope to realise an art project for those who typically have no access to global events of this scale.

Ive walked a lot in the mountains in Iceland. And as you come to a new valley, as you come to a new landscape, you have a certain view. If you stand still, the landscape doesnt necessarily tell you how big it is. It doesnt really tell you what youre looking at. The moment you start to move the mountain starts to move.

It would be wrong to say that the city of Berlin is not regulated. What I think is more interesting is to what extent a city creates a sort of safe haven for its users, so that people feel confident that the city works on their behalf.
