Reuters; Imagine: Lennon in TV ad 28 years after his death:

Through the use of digital technology, the former Beatle urges people across the United States to support a campaign by "One Laptop per Child" to deliver tough, solar-powered XO laptop computers to the world's poorest children.

"Imagine every child no matter where in the world they were could access a universe of knowledge. They would have a chance to learn, to dream, to achieve anything they want," a voice and video image of Lennon has been created to say.

Nicholas Negroponte's OLPC foundation says, "None of this would have been possible without support from Yoko Ono, animation from TAXI New York, and a little video wizardry with the lips from an awesome group in California."

For $399, you can buy two XO laptops -- one for yourself and one to donate. (Amazon is handling transactions for OLPC.)

Footnote. The OLPC wiki notes that, in November, "A highlight of the week was a visit to 1CC (OLPC's offices at 1 Cambridge Center in Cambridge's Kendall Square) by Tom Brady, quarterback for the New England Patriots, who came by to shoot a video for G1G1 ("Give One, Get One"). The XO amazed him. Brady asked if some machines could be sent to his sister's school in California, as well as a second shipment to his other sister, who is working in Uganda"

The OLPC blog noted that Brady's girlfriend, model Gisele Bunchen, "is from Porto Alegre (Brazil), one of our earliest school trials"

Here's Tom's video.
