WorldMapper

worldmapper.org is a site devoted to demographic maps. That is, instead of maps based on physical geography, they base the size of various nations on a give factor- population, income, religion, or what have you.

The religion maps are particularly interesting. Here's the world map oriented by Christian population:

... which is almost normal-looking.

The map oriented by Islam:

...in which North and South America shrink virtually out of existence, and Africa balloons to enormous size.

Oriented by atheism:

... Which is basically Planet China.

There's a lot more stuff there, all of it interesting.

Personalities and Places

Researchers have surveyed the US and discovered something really interesting: there are statistically-meaningful differences in the personality types of different regions.

There are several map-charts; it's interesting to look up your state and see how close (or far) you are from your state average. North Carolina is conscientious, friendly, and not very neurotic! Virginia, on the other hand... isn't.
