Yeah, you've found one of those easter egg things that people like me like to hide in websites like this one.
*waves hand slowly*
Go about your business, Move along.
Look, seriously, there's nothing here, really. Just click the back button and you'll be back in the real site.
You're still reading, well, I guess you're wondering why a π icon sent you here? right? Well, it's a reference to this film: http://en.wikipedia.org/wiki/The_Net_(film) Not that it was a great film or anything, it's just that the possibility of having "π" icons somehow hack into government sites was so Cool!
When I saw that, I was looking for πs everywhere. Never found any though.
