This challenge is simple. Write code that produces what looks exactly like a full reboot of the computer. It must not show anything on the screen that indicates it is not a real reboot and should finish at the normal log in screen you would get after rebooting.

Rules.

1. You can choose any OS you like to imitate. For example you can reboot into Linux from Windows or any other combination you choose.
2. This is a popularity contest so the cooler the better.
3. The code must in reality be completely harmless, perform no rebooting and be easy to quit at any point.
4. If you need to use external images to make the reboot look more realistic then your code should grab those automatically from the web.
5. Your code should be self contained, only relying on standard freely available libraries or tools, and easily executable by following the instructions you provide.
6. Good luck!
