Natural Pools

I have a feeling that a pool is in our future (far off in our future though), but when we do get one, I want to make sure that it is done in such a way that it doesn't distract from the natural "on the farm" look of our yard (once we get our landscaping done and it doesn't look like an abandoned lot).  Today one of the blogs I read pointed me to Natural Pools.  I LOVE the idea of these both for the aesthetics and the greenness of it, and although I have my doubts about how well it would do in the humid Florida climate, after a lot of positive research I would definitely consider putting in a natural pool.  Maybe by the time that we're ready to get a pool, these will be more mainstream with how everything seems to be going "green" nowadays.
