The Prey Project is an open source package that lets you turn your laptop or phone into a location aware spying machine, tracking its own motions, and reporting on the usage of the person in possession — screenshots, webcam photos, network captures, etc. — in the event that it is stolen or lost. Sounds great! Of course, it also lets you turn somebody else’s computer into a spying machine, so you can watch them, if you can manage to get it installed without their knowing. Kind of creepy… given that they’ve got a “pro” version that lets you track hundreds of machines simultaneously.
