Dead Musicians as Activists
In the Yoko Ono-approved OLPC ad, a digitally-enhanced John Lennon says, "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."
Implications - John Lennon is an iconic cultural figure whose identity transcends the bounds of the music world. He is related to campaigns that have a social slant. I particularly like this ad because it reinvokes the spirit of an icon that both younger and older generations can relate to. Have a look at the ad to see for yourself.
