File system that stores location of file in Pi
  Now, we all know that it can take a while to find a long sequence of digits in π,
  so for practical reasons, we should break the files up into smaller chunks that
  can be more readily found.

  In this implementation, to maximise performance, we consider each individual byte
  of the file separately, and look it up in π.

Definitely worth a chuckle. Very cute idea and implementation.
