First 10,000 digits of Pi, blue on black Swaddle Blanket

This design features the first 10,000 digits of the famous number and mathematical symbol, Pi. The numbers are written in white, over a black background. The Pi symbol is placed inside a blue circle. This is very important and symbolic, since Pi is derived from the division of a circle's circumference and its diameter. This simple division is puzzling, since it creates a non-repeating (yet), therefore irrational number. This number is the cornerstone of many branches of mathematics, and this design is the perfect gift for a math lover or engineer.
