'If I succeed working on a piece of art, it's been a good day for me. On the days when no art is produced, it's not a good day. We'll talk about a good day. What is most important to me is to make art.
I wake up at 7am as that is when my son wakes. I'm with my family until my son goes to kindergarten, at 9am. We use these two hours to do relaxed things, what most people do with their children in the morning.
At 9am, I go to my studio in Berlin, I have 30 employees. Normally from 9am to 10am, we have a meeting and plan the day together. I have breakfast with my staff and read my e-mails. From 10am, I work on art projects with my team until lunchtime.
We have lunch together; we always eat together. We have a cook and we try to spend some social time over lunch to talk a little bit outside the working context.
In the afternoon, we continue to work. My studio's like a laboratory, with a lot of scientists in it, and an architect and model makers. We create models in paper and wood and metal, and we experiment like in a small physicist's workshop.
We build a lot of things using the computer - we draw with it. I have six very good computer drawers - renderers [who] are trained architects. There's a lot of experimentation with light, colour, perception. We do cyber-physical experiments: we look at colours to [find out] when we know what colour we are actually seeing; how long it takes for something to register in the brain; how long it takes to see a tiger in the street.
