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

In many rural areas of the world, local communities use kerosene for indoor lighting, which leads to asthma, poor quality of light, and the desperate cycle of oil-based products that continually degrade the environment.

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.

I believe that access to electricity and light can radically improve people‚ lives.

My goal is to formulate a new color theory based on the full spectrum of visible light.

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.

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.
