Happy Pi Day
I have never heard of Pi Day before my American friend JudyO sent me a Happy Pi Day chat, explaning that is would make sense for an American, since they write their dates different thatn us Europeans – so 3.14 is the amount of Pi or more accurate:3.14159265358979323846 … you can use Google Calculator a pretty cool feature.
A lens has (of course) been created – a nice lens about pi – check it out at http://www.squidoo.com/PiDay, there is everything you ever wanted to know about Pi, even where to get a Pi tie 
Enjoy!
