Untangle is a Programmable Ink research project done at Ink&Switch, together with Marcel Goethals, and with engineering help from Mike Kluev.

This project was an exploration of a visual language for describing, and solving, constraint satisfaction problems.

As usual, there's a long essay documenting our goals, decisions, learnings and failures. Enjoy!

Untangle was presented during my 2022 Strange Loop talk.
