The rick roll scripts:
 - rickroll.bat 
	just starts playing immediately. Useful if someone has a headphone and an unlocked PC.
 - rickroll2.bat
	Starts playing as soon as the mouse moves (even if the terminal window doesn't have focus). Hide it by alt-tabbing to another application. 
	When the user returns and moves his/her mouse, it starts playing.
	Useful if a user has speakers
