They Rule "aims to make some of the relationships of the elite of the US ruling- class visible". Track from a corporation to its board member and on out, to see who is actually ruling the world. Incredibly useful and done with a fabulous interface. And you can add notes and maps of your own. Gotta have flash, sorry. Very worth checking out.
For a quick example of how it works, click on "load map" and then click on the first one, the most popular, "pepsi vs. coke" to see just how snuggly close they are.
