An Artistic Approximation Of Pi. Now in a Hoodie!

What is Pi? Some might define it as the ratio of a circle's circumference divided by its diameter. Others might think it's an irrational number that's impossible to know completely. Still others might think it's a mystical, transcendental, almighty number that will only finally be revealed when society as a whole puts on a bunch of purple felt jump suits and hitches a ride on a nearby comet. We know it's one of our favorite numbers, and that's gotta be good for something.

50/50 cotton/polyester 9.1 oz hooded sweatshirt with drawstring hood and "unipocket" in the front with the Pi symbol printed on the front in white. A whole bunch of digits of Pi were used to construct the Pi symbol itself. Ok, we admit it, we didn't count the digits for the hoodie. A big shout out from ThinkGeek goes to Archimedes way back in the B.C. for finally giving us a good approximation of Pi, and doing so without the benefit of modern trigonometry. And thanks to the Egyptians and Babylonians for trying.
