Do you have a gps sensor? Joe has one, and mine is being sent to me now. Sooner or later, we’ll install GooPs and start tracking where we are. (Creepy….) but no, really, GooPs lets you track GPS sensors on google earth real time. It even allows collaboration by tracking other people in the same network. It will leave a colored mark of where the sensors have been, and it even tells you its travel speed. Its a cool bit of program. Check it out: GooPs
