I saw a history channel show not too long ago about how the Japanese are designing a new self-sustaining sky city, or something like that! It's been a while, I don't remember exactly, but it was something like 2 or 3 miles high and every "floor" was circular with apartment-offices, farmer's markets type, etc. Each floor, if I remember correctly, would it's own mini-city. It was amazing, but the city planners in Japan were saying that this building would not be just something new and different, but a strict necessity at one point because of Japan's over-population.
