You might have heard about the Million Dollar Homepage where a Alex Tew sold pixels on a 1000x1000 grid on his website thus making him over a millon dollars, an idea which falls both into the 'Why didn't I think of that' and 'there's one born every minute' categories, however there is a site out there that loosely takes the idea and turns it towards a much better cause.
From the Darfur Wall website itself:
The numbers 1 to 400,000 cover the 40 panels of The Darfur Wall. Each number represents a person killed in Darfur. By donating $1 or more you can light a number, turning it from dark gray to brilliant white. As we light the wall, we acknowledge the importance of each life lost, we cast light upon a tragedy too many have ignored, and we overcome one barrier to peace.
Its sobering to think that each number represents a human life lost, please promote this site where and when you can, it would be nice to see that wall brightly lit.
Strangely although I came to the site via Digg there is a SharePoint connection to this, the site has been setup by Jonah Burke ex of the MOSS BDC Team who I happened to see speak at TechED in Boston.
And what number did I pick? In true geek fashion 443 of course.
