Using the freeware app iAlertU that works as an alarm system for your MacBook, along with a Mac FTP app called Transmit, Adam shows you how to set up a script that will use the MacBook's bulit-in iSight camera to automatically take a picture of anyone who moves your laptop. Then it'll FTP that shot to a site of your choosing. Take a look at the post for full instructions.

If you can use a script to automatically FTP shots, it stands to reason that you might be able to do a similar routine to trigger an alarm to auto-upload with Photo Booth, too. Cool stuff either way. – Charlie White

How it works: iAlertU will detect when the Mac is stolen, which then activates the iSight on your Mac to take a shot of the thief, then triggers Applescript and Transmit to upload the picture to your website. After grabbing the shot off your website, you can send it to sites like Gizmodo or Lifehacker to ask the internet community to identify the guy and get your laptop back. Not a bad idea to make sure your $1500 doesn't turn into $0.
