The pixels on the right are organized by time of death. From Flickr description, “This is to show you can dilute the media impact of a massacre by killing a few people each day for 6 years. Just remember that host nation + civilian + enemies = mostly Iraqis.” The intention is to show what “noise” could mean if ordered.( Source 1) (Source 2)
There’s not a lot to go on here as far as concrete numbers, but there are some pretty obvious inferences which can be made. First, there are a LOT of pixels there. A lot of dead people. Second, FAR more civilians have been killed than any other group. Note how many of the civilians have been kills since the initial push. Finally, there are nearly as many host nation (Iraqi Government) and Friendly Fire deaths combined as there are enemies killed.
