I decided to release my ARNT research project from 2017-2019 as OFL. Borel is a typographic system for french primary school teachers. You can use whatever favorite app to translate the doc from french: https://github.com/RosaWagner/Borel

Maybe one day I'll have the motivation to add the entire research report I wrote at the time.

I don't plan on releasing the roman counterpart I designed for Borel since it was pretty uninteresting.
