Bluelock is a small bash-scipt. Bluelock is written to check if a bluetooth device (ie a mobile phone) of you is available, if it's not it will lock your computer. So the idea is that if you walk away from your computer and you forget often to lock it, this script will do. But on the other hand if you stay near your computer, it won't lock, because you are close to him.
