I just spotted THIS topic over on Haarkens blog and think it would make a fantastic scenic addition to my Leviathan project!
Floating Islands by Haarkan
Its been used in films like Avatar and Dragon Hunters and could make for a really interesting game. Imagine the whole board consisting of a series of such islands slowly drifting randomly, sometimes bumping into each other or floating off the board entirely! It would make for a really interesting game with the forces trying to navigate the islands.
I may have to give it a go once I have some time!
All the best!
