Imán Math geek Pi symbol, blue circle and digits.

Pi is an irrational number obtained by dividing the circumference of a circle by its diameter. Such a simple operation produces such an amazing and interesting number. This design celebrates Pi, and is a great gift for mathematics geeks and nerds. The design features the Pi symbol inside a blue circle, and the background of the image is created by the digits of Pi, so there is a nice interrelationship between all the elements in the design.
