Personally I do not have much interest in neither football nor the currently running world cup (the 2010 FIFA World Cup) but I have to admit that Metia's World Cup Pivot application is a very nice Silverlight application. After playing a bit with it the only thing I miss is some kind of tooltip when moving the mouse over the picture of a player (or maybe just some information embedded  into the picture of the player). Having to zoom a players picture to see who he is seems a bit cumbersome, but overall it is a very nice application. The reason that the World Cup Pivot application works nicely though is probably simply due to the fact that it is based on the The Silverlight PivotViewer control. A control you can use yourself when creating similar applications.

Now I just have to get my hands on some interesting data so I can create my own pivot application...
