Infinity pools! I am a big fan and whoever had the very first idea of infinity pools was a genius. Hats off to you!
As a water-lover (seas, pools, and any kind except those rivers which obviously have something living on them particularly gigantic reptiles), i always see water as a symbol of relaxation.
Infinity pools are better if the view is also a sea or a horizon or a rain forest. But there are some which are perfectly built that you wouldn't mind having a view of man-made structures. Here is one example. I've been here but never got the chance to swim. I did more of a sight-seeing.
And oh, natuuuuuure...
