Taylor Swift [ tickets ] made a surprise appearance at the Consumer Electronics Show in Las Vegas last night (1/6), during which the country wunderkind gave a one-song performance that helped demonstrate Sony's foray into 3D video.

"I feel like my fans are all very cutting edge, so when it comes to technology, I'm very interested in what's the newest and best," Swift said during her appearance as part of Sony's CES presentation. "My tour starts up next month in Australia and Japan and I'm very much looking forward to documenting all of that behind-the-scenes and on-tour footage using 3D."

YouTube footage of the event, which is included below, shows Swift and her band performing the cut "Love Story" with a massive video screen behind them, on which the 3D footage was shown.
