A live solar system on your desktop....
OSXplanet is a cocoa program that is based on the popular program, xplanet (by Hari Nair). It is able to generate live images of the earth as well as other planets in the solar system with additional informations such as the current clouds, storms, satellites, volcanos, earthquakes and times and locations of cities.
Only for Mac. Too bad, it looks cool.
just noticed the dates too....it has been around a while....
Yeah, I had that for a while. It ended up getting too distracting for me to have a changing desktop ;).
