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.

Having an experience is taking part in the world. Taking part in the world is really about sharing responsibility.

I want to expose and evaluate the fact that the seeing and sensing process is a system that should not be taken for granted as natural - it's a cultivated means of reality production that, as a system, can be negotiated and changed.

I see the artist as a participant, a co-producer of reality.

When museums are left with so little money that their future is in the hands of private donors, then they are unable to develop their own signatures by collecting themselves. On the other hand, though, I think we should also celebrate the fact that there is a lot of art that lives outside of, or on the outskirts of, the art market - and it is doing quite well.

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.

Every city is always changing, on its own trajectory.
