Ok, that sound vague. Let me explain what this is exactly: it’s a Flash application where you can select companies and view their board of directors. That is not too interesting. Then you can select on what other board of directors they are. That becomes interesting. And then… you can select a x-degrees-of-separation from some other company’s board of directors. Sort of a chain of command. And that’s really interesting.
Also check out the who owns what in media companies. This can explain a lot when you’re browsing and you see ads that you wouldn’t expect.
