Do you like the Portal games, and have always wanted to own a Sentry TURRET???
Now it's possible and it's totally free with this interactive motion tracking version.
You only need a computer and a webcam. :D

How to use?
1. Allow your webcam usage to the program.
2. Step back to give some space to the turret.
3. Hide somewhere or move, the turret will react to your moves.
4. It'll keep your room from intruders, until you turn it off.
5. Enjoy!
