This is an interesting way of presenting knowledge. Meet Globe4D: an interactive installation for globe viewing, used by museums, schools and universities to exhibit or discuss knowledge. It is possible to show changes over time, climate differences, air plane routes… I like the way this tool makes the Earth (or another planet) more tangible. It works like this: the planet is projected on a sphere. By rotating the sphere it can be observed from any angle. A ring, fitted around the sphere, allows the user to manipulate the fourth dimension by turning it. This can be time or any other variable (e.g. waterlevel, zoom). The installation was originally developed in a researchgroup at the University of Leiden in the Netherlands. I can see the use of this for many institutions and exhibitions!
