And if that isn't crazy enough, check out The Aquaria Grande in Mumbai India. A 37 story residential tower with swimming pools on each balcony. Yes, you read that correctly. I wouldn't want to be the guy who insures the glass surround, and I can bet there is absolutely no "cannon balling" allowed here.
Lastly, check out the Vertical Forest, which is currently being built in Milan, Italy. When completed, it will not only look incredibly stupid, but will also use so much steel and cement to support the weight of the trees that it will counter-balance the whole idea of "going green".
Would you live in places like this? My blood pressure is through the roof just thinking about swimming in those pools and trusting that the glass wouldn't crack while I was gracefully back-stroking my way around.
