Viral Video: Get Out Your 3-D Glasses for the Michael Jackson Grammy Tribute (Plus Colbert and the iPad)

While an iPad out in the wild–held up by Stephen Colbert–got a lot of ink, here’s a video from last night’s Grammy Awards, which went all “Avatar” during a tribute to the late Michael Jackson–when a panoply of belt-it-out singers performed one of his posthumous songs with a 3-D twist.

In fact, much of the audience was wearing 3-D glasses–including Beyoncé pictured here–to properly experience the performance of “Earth Song” and its accompanying film, which was supposed to be part of Jackson’s “This Is It” tour.

Celine Dion, Jennifer Hudson, Smokey Robinson, Carrie Underwood and Usher sang the piece, along with a recording of Jackson.

Special 3-D glasses were also available at Target for home viewers of the music awards show, so if you still have them, use them for this video from the television show–and below it, Colbert with the new Apple (AAPL) device:
