This is the end: Countdown to Dec. 21, 2012 begins

We hate to break it to you, but a year from today, the world will end.

OK, technically, the Mayan long-count calendar ends on Dec. 21, 2012, and the day may just be another shopping day before Christmas. But what if? In that spirit, we're throwing some of The Doors your way to begin the countdown in a cool, trippy rock way.

And if the world does end, at least we can say we told you so.
