Lock your Mac like a car

Here is an interesting application which uses the sudden motion sensor in a MacBook Pro to detect any attempt to move your Mac.

This would be perfect for situations where you would have to leave your Mac for a few minutes to go to the toilet or similar. Any unsuspecting Mac thief would get the surprise of their life when trying to pick up the Mac.

Although, if the Mac were accidentally bumped, it would certainly cause a commotion...

There is a video too.
