Prey:: for your stolen Laptop

Prey helps you find your stolen laptop by sending timed reports to your email with a bunch of information of its whereabouts. This includes the general status of the computer, a list of running programs and active connections, fully-detailed network and wifi information, a screenshot of the running desktop and — in case your laptop has an integrated webcam — a picture of the thief
How it works
When you install Prey, you set up an email address and optionally a URL (i.e. http://mypage.com/stolen_laptop).
Prey runs at a specified interval and checks the URL you previously defined. If the URL exists, Prey will gather the information and send it to the email address you set up. You can also not define a URL and in that case the program will send the data every time it runs.
Of course, Prey needs to have an active Internet connection to send the information. If the computer isn’t connected, Prey will attempt to connect to the first public Wifi access point available


Its avaiable free for Linux,Mac & Windows,under the GNU licence v3.0
