This Friday, James Nachtwey reveals his TED Prize wish. They will be projecting images on LED screens at locations on all 7 continents, along with the website- watch if you can, this promises to be an important story.

Watch James speak about his wish:

Each winner of the TED Prize receives $100,000, and assistance making their wish come true. Other winners of the 2007 Prize were Bill Clinton and EO Wilson. You can find out more about their wishes, and many other past recipients as well, at the TED site– there are some really great talks (also available as podcasts) on there, worth checking out.
