Wow, this is great! These are very organic-looking, especially with Handwriting, Brush, Wiggle, and both "round" options toggled on. I'd love to see an option to export to TrueType or some other vector font format. Even just .svg would be good, I could probably find a way to get .svg characters into a font...
It'd be extra cool to be able to choose to use a set of these runes for the titles on a map from Perious Shores or MFCG -- which would be easy enough if they could export to a font.
