While an iPad 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.

Indie rockers Nataly Dawn and Jack Conte are pioneers in the new VideoSong movement, soon to hit a computer near you. The Stanford University graduates in the summer of 2008 formed the band Pomplamoose, recording high-energy video covers of popular tunes like Beyonce’s “Single Ladies” and Michael Jackson’s “Beat It.”
