Pi pattern for smart phone case

I became an owner of the first smart phone and decided to make a special case for it.

This is created using bead rope technique. Pattern here is not random as it seems. This is a very mathematical thing. Remember pi = 3.14 which we know from school? These days π has been calculated to over two quadrillion decimal places and still there is no pattern.

My phone case uses about 600 decimal places of π.
