The code here implements the virtual machine and I expect perhaps some solutions to puzzles from the following infamous programming contest.

CBV was an amazing programming contest associated with ICFP 2006 which is now archived at boundvariable.org and is so fun, people evidently still like to try the puzzles.

The first task is to implement a virtual machine as specified in ancient stone tablets recently unearthed, or so the backstory goes.

Once the VM boots with the provided image (after much debugging) the main sequence of puzzles is revealed in a hilarious adventure.

You might like to use clueslurp, my streaming command-line filter for grabbing the "publications" which appear in the console output, signifying each achievement unlocked moment.
