Since today is March 14, which in numerical format is 3.14 - it is Pi Day! Pi is the ratio of the circumference of a circle to its diameter. Pi Day is celebrated by math enthusiasts around the world and bloggers here at Spreadshirt. The Spreadshirt German blog has a little contest running match the employee to their gadget.
Here in the US I have created a few Pi items for the occasion - yes we have a Pi symbol for you to use.
I created a track jacket with 3.14 on the front and the pi symbol on the sleeve. I like to think of this as a subtle geek chic.
Other ways to celebrate Pi Day - Wikihow has a whole page of ideas. Which includes watching the movie Pi and getting married on Pi day to show that your love is forever. I love that people make Pi Pies (and cakes and cookies) - there are tons on Pi Day photos on flickr including some homemade Pi Day t-shirts too.
