The data used for counting deaths per Baghdad neighborhood comes from the Iraq Body Count Database. This count includes civilian deaths caused by coalition military action and by military or paramilitary responses to the coalition presence, as well as excess civilian deaths caused by criminal action resulting from the breakdown in law and order.

Neighborhood locations were organized according to a map entitled U.S. and Russian military maps of Baghdad (2003), as obtained from the Geospatial Library, Harvard University. The neighborhood list was verfied by hand with an image of a 2003 NIMA map of Baghdad, as found on globalsecurity.org. This list is compared to the Iraq Body Count tallies. A large effort was made to accurately count deaths not listed in correlated neighborhoods. Articles were read for location based clues (e.g., markets, universties) and research was conducted to decide alternate spellings.

These neighborhood counts are placed over the Boston Area by transferring the center of Baghdad to MIT. The translation of GPS coordinates was accomplished with the help of the GIS Laboratory, MIT. Further work and documentation of this process will be available soon.

Circuitry includes a small microncontroller for memory and actuation, a GPS module for location, and a motor for releasing confetti. A program on the computer chip stores the Boston-Baghdad coordinates with the latest media reported deaths. Once in one of these "hot spots," the microcontroller queus a motor, which eventally punctures a small CO2 canon. The force of this action releases a cloud of confetti inscirbed with the names of the dead.

The great uncertainty of all data in war is a peculiar difficulty, because all action must, to a certain extent, be planned in a mere twilight, which in addition not infrequently - like the effect of a fog or moonshine - gives to things exaggerated dimensions and unnatural appearance. -- Carl Von Clausewitz
