Pombo
A GUI can be found here : https://github.com/BoboTiG/pombo/tree/master/gui
Pombo can help you recover your computer in the event it's stolen. It works on Windows, GNU/Linux and Mac OSX. How does it work ? Pombo works silentely in the background, hidden, and sends tracking information to a webserver of your choice. If your computer is stolen, just log into your webserver to get the lastest file uploaded by Pombo, decrypt and hand it to the police. They will have all they need to catch the thief: IP address, date/time, nearby routers, screenshot, and even a photo of his/her face if you have a webcam ! Pombo protects your privacy : Tracking information is encrypted with rock-solid GnuPG and only you can decrypt it.
