Using digital technology to recreate Lennon's face and voice, (OLPC) created an ad, promoting its cause. The organization to children in developing nations.

Digital Lennon riffs on Imagine, his most famous song, as he "talks" about changing the world. "I tried to do it through my music, but now you can do it in a very different way. You can give a child a laptop and more than imagine, you can change the world."

OLPC , including of the New England Patriots and of the NBC television show Heroes to promote its cause. But apparently the organization needs dead celebrities to really make a difference -- or perhaps it is just trying to tap into the wallets of Beatlemaniacs.

This isn't the first time corpses have been digitally dug up for modern purposes. Remember when Celine Dion ? Or when Fred Astaire danced with a Dirt Devil in 1997? It was creepy then; it's creepy now.
