Hey jan Same!
You can see it in action here: http://nullelement.org/2015/05/living-toki-pona-using-flexbox-layout-and-sitelen-sitelen/
I left the project in its infancy, mainly because of a lack of motivation to create all the vector glyphs myself and second I didn't have a nice set of example sentences to test my algorithm on.
You, my friend, have now given me both: vector glyphs (prettier than mine) and a nice chapter of sentences to play with. I think I will reboot my project once again!! Thanks!
BTW I also started on a kind of mindfulness/toki pona learning app that not only uses sitelen sitelen for text but also uses the word glyphs instead of standard UI icons such as 'back', 'save',' share', 'ok', 'cancel'. After all, a full set of icons can also be seen as a minimal language.
