William Snyder III manages an art project to commemorate the 800,000 Rwandan's killed in 100 days in 1994. One page for each person, bearing the muddy prints of participants around the world, are sown into 250 books displayed in 100 crates, one for each day of the war. The participants also have raised milions for the Rwandan The Kayinamura Foundation.
This bears great resemblance to what I am trying to achieve with my thesis work on Iraq. It's a wonderful actualization of such a horrific and inconceivable number.
