I am a Ph.D. student and that means I have a question: how can we make digital content graspable? Because you see, on the one hand, there is the digital world and no question, many things are happening there right now. And for us humans, it's not quite material, it's not really there -- it's virtual. On the other hand, we humans, we live in a physical world. It's rich, it tastes good, it feels good, it smells good. So the question is: how do we get the stuff over from the digital into the physical? That's my question. If you look at the iPhone with its touch and the Wii with its bodily activity, you can see the tendency; it's getting physical. The question is: what's next?
