Undrium reads styles from this folder. To add a new style:

   1. Copy the folder called Default
   2. Paste it into the same folder
   3. Rename it to a name of your choice
   4. Edit the graphics in that new folder
   5. Run Undrium and pick your new style

Email rich@bitglint.co.uk if you would like your style added to the game
for others to download via the Update menu option.

Be aware that doing a content update from the game menus may overwrite
your folder contents if you've chosen a name that's likely to be used
by others.
