I used a US FB account to have a look but all I saw was an application only link via the example page, so I have to wait to be accepted.

The "Try a Search" link here https://www.facebook.com/about/graphsearch  HTTP requests .... on first impression can be manipulated to do your own examples, first by altering the user id variable and changing it to your own, but i didn't want to suck up too much time looking into it. Besides I'm sure it will be genereally available soon.
