Which book is on the top left hand corner of your bookshelf?
That’s where my wife’s books are – that’s her section of the bookshelf – which means mostly language guides for Serbo-Croatian and Russian. In my section, there are predominantly works by Neal Stephenson and William Gibson, mostly in German and English. What do you do on a surprise day off? If I don’t feel like looking at a screen, then I play with my synthesizer. And if it has to be on a screen, then I keep working on my virtual bird simulator: I can fly through virtual landscapes with it.

What do you do to make the world a little bit better?
I try to write programmes with which other people can be creative – as open source projects. I make training videos available and lead training sessions, for example, for students. I want to empower people to design actively instead of just consuming.
