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

I always try to make work that activates the viewer to be a co-producer of our shared reality.

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.

I think an artist has the potential to investigate both form and content within one activity, to show that there can be coherence between form and values in our society, as in thinking about a city and building one.

I don't know a single collector or museum director who says: 'Oh, he's on a list, so I think I'll buy something of his.' The people who buy my art put a little more thought into it than that.

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.
