Is there any way to disable a secondary Cinema Display without unplugging it?

Hi guys,

I have two of the 27inch Apple Cinema Displays on my desk and the only time I use the secondary display is when I'm coding, working in a game engine, or doing 3D work. The rest of the time its a distraction because I always stick facebook and adium in it. I was wondering if there is a way to disable it for when I don't need it (without unplugging it).
