Open source satellites

Following on to some of the open source tracking thingies I have featured on these pages, I now grant thee NASA J-Track 3D, a fun little java satellite tracker thing that let me experience the stellar meeting of British UO-11 and Soviet Cosmos 1812 high above the heath of western Jutland.

I don't think this will show any spy-satellites, though. Not American anyway. But fun never the less.
