I've got this idea for a square center piece of 'land' with each side the same length as one of the Ares 'coast' pieces so that it would be possible to add a 'coast' section to each side and therefor make a fairly large island with noticeably different terrain on each side. I guess some fairly thick card or even plastic sheet painted or colored to approximately match the Ares pieces would be the best option. What do you think, workable?
