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: 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.
