For the sake of sanity, the brain and the eyes keep things simple. But take away the sense of sight and suddenly things are not so simple.

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

I don't think you need to be so result-oriented when you're trying to define the success of an art work. I think we can allow some unpredictability.

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.

Over the years, in making art, I have constantly explored issues dealing with space, time, light, and society. I am particularly interested in how the light of a space determines how we see that space and similarly, in how light and color are actually phenomena within us, within our own eyes.

In the past Berlin was much more radical and extreme and now it's becoming much more of a conventional European city.

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.
