A Truly Amazing Dot Density Map of the US Population

My older son alerted me to a blog post by Chris Welch about a recently created dot density map of the US using 2010 census data. Now, to be sure, the Census Bureau has created one of its own, which you can download in PDF format, but this new Census Dotmap is truly amazing. It is online, it allows you to zoom in to micro-level areas, and it has a background map so that you can orient yourself. It was created by Brandon Martin-Anderson, a student in the MIT Media Lab, and the website he created for the map includes details of how he created it. You simply have to see this to believe it.
