About
A hash function maps arbitrary data to a fixed-size value. Usually, that value is a mere number. However, HASH is no usual hash function. No, HASH spins up a whole new operating system and then bends and fuses together scripts — both of my own and of my fellow students — and spits out a brand new image.
NOTE
I may have bent the definition of a hash function a little. HASH doesn’t produce values of fixed-size in bytes, but in resolution.

Code Snippet
My favourite piece of code from HASH: a bash function that starts a simple http server, runs Firefox on a given p5.js sketch, and waits until a valid PNG file appears.
