The Most Well-Rounded Holiday!

Today is Pi Day, the best day of the year (well, it's in the top 3.1415)! Pi Day was created to commemorate the mathematical constant π (pi), and it is celebrated today because March 14 is written as 3/14 in the month/day date format.

The Picycle was created by Tang Yau Hoong, and if you like it as much as I do, you can buy prints here. It's a must for math-geeks who also bike!
