Navigation through information available on the world wide web and other large datasets nowadays is a one-dimensional task: The whole world of information spans between the "backward"- and "forward"-button of your favorite browser. "Going" back to a piece of data you spoted a few minutes ago forces you to predict the number of times you would have to click on one of these buttons in order to get there.

We dream of a truly threedimensional information space, making movement in it as natural as walking through a city.
