James Nachtwey's TED Wish

I don't know what James Nachtwey is working on for October 3rd, but if he's delivering it, I'm there. As you probably know, winners of the TED Prize are given the opportunity to fulfill a wish. Control Room director Jehane Noujaim, for example, decided on a concept of international short-film sharing, which turned into Pangea Day. What we know about Nachtwey's project: 

James Nachtwey is preparing to reveal his photographs, which highlight a shocking and underreported global crisis. Over the past 18 months, the TED community have been working with James to gain access to locations he wished to photograph, and to prepare spectacular plans for unveiling these pictures.

Here we learn that the results of Nachtwey's project will be projected on buildings and shown on screens in public all around the world at the indicated times and places.
