Awesome visualization of data
Id say this is right up there with the app that lets you track visible constellations based on your location. Not especially useful every day, but definitely fun to play with.
The app is pretty self-explanatory (not sure why someone was confused in their review about the satellites orbiting the planet...), and pretty cool to show off. Even more impressive when you consider the data is petty much real-time.
