I visited the Heureka science museum today and they had this amazing, animated globe hanging in the air.
I was told it's technology prepared by the American NOAA organization. Four projectors carefully aligned to make the globe act as one screen. The resolution was sharp and the experience is flawless. One can walk around the globe and study it from any angle.
They presented multiple data sets, some having to do with weather (in the picture). Others showing flight patterns and even individual airplanes depicted as little beams of light. The globe can be span around using a Wii remote.
Even better, this Finnish invention could be used to roll the globe, and even squeeze it! :)
