Many Many Digits of Pi Mathemathical Constant Neck Tie

Add a little inspiration to the office -- or office party -- with a "Pi Tie", which features an oversized Pi symbol overlaid with many digits of this mathematical constant, rendered in a 60s OCR-style punch card font. Reverse shows identical design.

Pi (π) is more than a number with an infinite number of digits behind its decimal point. Whenever you see a circle in the natural world, Pi is involved. The hard sciences, medicine, music, statistics, navigation and much more depend on pi to solve the challenges of their respective fields. There is even a Pi Day--March 14--to commemorate this remarkable mathematical constant.
