Friday March 14 is π Day. MathematiciansPictures.com has all the gear you need to celebrate, including mugs, T-shirts, and posters. They come in one of two designs: π around the world, and a special design for 2008 featuring Isaac Newton.
When 3.14 finally arrives, head on back to Mathematicians Pictures at 1:59 PM Eastern and 1:59 PM Pacific to watch the official Pi Day Drop of the Giant Pi .
And if your Girl Geek really loves pi, sign her up for the π of the month club!
