Realised I haven't been updating this as I went along. These are some of the fonts that I've been experimenting with. I think I will be sticking wit the Voyager font as it works for what I want, but the others might also be support fonts for different systems.
The reference images I've been most interested in involve layered systems such as plants and leaves. I want to look at a way they can create a branching system within the final piece.
