Technological advances.It's amazing what we can do nowadays. Read here about a skyscraper proposed for Dubai that has each floor able to rotate so that it will have a different look every day. There are plans to build another in Moscow.
Cool or what although I wonder how people will feel in a corner office. Obviously it will make the view interesting although I wonder it will induce motion sickness even though it won't be moving very fast. Between 1 to 3 hours for a complete rotation of each floor.
Won't be a problem for me though. Cheapest apartment is $3.7M with the best ones going for $36M. That is a hell of a price difference.
