The rather unfortunately named BOOMsys is a Google Map of improvised explosive device incidents in Iraq.
BOOMsys actually stands for Basic Ordnance Observational Management System and they have created a very impressive map displaying all the improvised explosive device incidents in Iraq in 2006. The map features an animation control that allows you to view the data over the full year.
As well as the animation controls BOOMsys includes a calendar navigation control that allows you to view the incidents for any month, week or individual day. The size of the polygons shown on the map reflects the number of incidents recorded at that location.
