John Lennon's image and voice have been digitally recreated to support One Laptop Per Child, which donates rugged, solar-powered laptops to children in developing nations, according to The Washington Post.

In the advertisement, which was approved by Yoko Ono, Lennon's song "Imagine" plays in the background while the digitized deceased Beatle "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's previous spokespeople have included Tom Brady of the New England Patriots and Masi Oka of the NBC television show "Heroes." This is the first time the organization has reached beyond the grave to tap a celebrity supporter.

Lennon was shot to death in 1980; the first commercially available portable computer debuted in 1981 and the first portable computer using the term "laptop" was released in 1983, as cited on Wikipedia.
