## What it is
πfs is a novelty FUSE filesystem written in C that 'stores' files by finding each byte's offset within the digits of π, using the BBP formula to look up and extract data. It is a humorous proof-of-concept based on the conjecture that π is normal and contains every possible finite byte sequence.

## Use cases
- store files in pi instead of disk
- novelty filesystem demo
- learn how FUSE filesystems work
- demonstrate the normality conjecture of pi
- joke about 100% compression
- explore BBP formula digit extraction

## When to choose
- you want a fun, educational FUSE filesystem example
- you want to demo the idea that pi contains every possible file
- you're exploring filesystem development in C

## When to avoid
- you need real storage, performance, or reliability
- you want actual compression or space savings
- you need a filesystem for production or daily use

## Facets
- artifact type: application
- maturity: experimental
- function: file-system, compression
- domain: files, developer-tools
- platform: cli
- tags: fuse, joke-software, novelty-filesystem, pi, bbp-formula, algorithms, linux, macos
