Hi there,
by using the WYSIWYG theme editor, I made some exotic themes, feel free to use, modify it.
- bergfex : bergfex inspired theme
- fantasy : theme inspired by "lord of the rings" map
- historical : black & white map, maybe cool for you E-Ink display
- noir : dark themed setting
All themes are previewed in this video:

Again, you are free to use and modify whatever you want, I'll take no credit.
