Imagine an app that let’s you spy on the person that might have stolen your laptop. It’s called Hidden. If your computer is stolen, Hidden will show you where it is and who has it. When you activate tracking, Hidden will locate your stolen computer anywhere on the planet, collect photos of the thief and screen shots of the computer in use.
One Hidden user started a Tumblr Blog with the images the app was able to collect. Slightly awkward to look at the person who is using your computer.
