### Pi Day

A tartan for today's special date, March 14th, also known as Pi Day, for the transcendental number, starting with the digits forming today's date (in the month/day/year system) = 3.14159 ...

Recall that pi is the ratio of a circle’s circumference to its diameter.

By designer Carol A.L. Martin "this whimsical tartan was created in honour of"Pi Day" March 14th, 2010. On that day mathematicians celebrated the calculation of pi to more than 200 billion digits by supercomputers! In this design, all colours begin with the letter "P".."

Pi (uppercase Π, lowercase π) is the sixteenth letter of the Greek alphabet, representing [p]. The letter "π" is the first letter of the Greek words "περιφέρεια" 'periphery' and "περίμετρος" 'perimeter', i.e. the circumference.

The designer used the colours: Pewter Blue, Pacific Blue, Privet, Pineneedle, Pastoral Green, Pastel Green

Note: 6 years later, the record is 13.3 trillion digits.
