Lockdown

Lockdown is a free solution to going to the bathroom while working on your computer in the library. Essentially, if somebody touches your computer while it is activated it does 3 things:

• Sets off Alam sound
• Takes a snapshot (and emails it to a specified address if you want)
  
• Locks down the computer

So next time you set up camp on the 3rd floor and get that sensation, you may not feel the need to pack everything up and take it with you.
