I firmly believe that having a work-only website makes a web presence sterile. The person matters -- otherwise how can you decide whether you want to work with someone? Or how to get to know someone?
So here are a few more personal aspects of my life:
After school, I couldn't decide whether to study computer science or psychology. I finally decided to study psychology, because computers were too easy (they do what you ask them to do, don't they?). I did take a few courses of computer science during my time at the university and found out that computer science was a little different than expected and that the choice was the right one (and not only because cs was not for me). Still, I have a high technological affinity -- among others, I know how to program simple apps and old-school HTML code (like this site). And given that I often try out things first-hand, I know the limitations of technology very well.
I love science -- although not so much the way it is often conducted. Still, it is the best work (and play) for me. I love conducting research and I am interested in getting to know different disciplines -- one of the reasons I love TED talks, Coursera, Improbable Research (esp. the "first make people laugh, and then make them think" part), and much more. Related to science, I also love teaching -- be it in a university course, student conferences, workshop for student organizations or just for fun. You find more on my stance on teaching in this self-reflection (in German only).
I found that taking a camera with you, esp. on conference trips, allows you to see more than you would otherwise see, and thus I have become an avid photographer. Among others, I love street photography and portrait photography.
I also love writing and creating books, having written both fiction and non-fiction books. I also enjoy doing mashups, for example, a 400 pages book of quotations. It is incredible what you can create when you combine a good DTP program like InDesign with a book-on-demand service like CreateSpace or Lulu.
