Subject: [AZ-Observing] Census Dotmap and Light Pollution

This is only sort of on-topic for this list, but it sure looks like a light 
pollution image.  In fact, it's a representation of the 2010 census data as 
308,450,225 individual dots.  Zoom in, and it becomes a sort of grayscale image 
of population density.
