Pi Day

Today (2007-03-14) it's the Pi Day. If you were a strong Pi fan you could celebrate this day on 1:59pm (commonly known as 'Pie Minute') just because Pi is rounded out to five decimal places - 3.14159 there.
There exist also an official Pi Day website where you could also submit a comment why you love Pi.

Never forget to mention that today it's also Albert Einstein's birthday.
