is this opensource? adding a cool fluid simulation to whatever you draw would be really fun. its like one of those ioccc vids - https://www.youtube.com/watch?v=QMYfkOtYYlg

Very interesting one! So many cool things have been made in this field! However I think it's not relevant for the board. It's not open-sourced (at least yet).

Anyway thank you for checking it out and suggestion!
