Happy Pi Day with Pi Out to 1000 Digits Pin

Pi Day Pin

designed and sold by  Scarebaby

1000 digits of PI, starting at 3.14. Embedded within are the words HAPPY PI DAY in red, easy to see! Funny math pi day t-shirt makes an excellent gift for mathematics, geeks, nerds, teachers, students, puzzle lovers and smart people. Pi Day is always on March 14, because 3.14 are the first numbers of the mathematical symbol pi. People celebrate Pi Day by making puns, making (and eating!) pies and wearing cute graphic tshirts. Created by Scarebaby Design, a registered trademarked brand. You may not reproduce, copy, or otherwise re-use this design in any format for any purpose, especially for commercial purposes.
