Thanks! We're a student group running an open puzzle hunt for medical/biomedical students who want to learn or practise coding. This is one of our puzzles based on a simplified cell automata model of a single heart ventricle.

We use Elm on our frontend and plan on using it to make other interactive puzzles like this one - we originally got into Elm from HN and it's been a joy to work with, so we wanted to share it back!
