Check this out: A Tower To Change Its Shape Every Hour.
Apparently, an Italian-Israeli architect, David Fisher is planning to create a tower in Dubai that will have rotating floors. Makes me think of that series of horror films about a people trapped inside of a Rubix cube like cage that would change and move at regular intervals.
As cool as the idea sounds, it give me pause, too. For one, it seems that it could be rather dangerous to navigate inside the building, especially when its rotating. Also, in order to do this, the floors will be donut shaped, which means there will be wasted space on the inside of the building. At a time that global climate change is getting some serious press, is it really wise to be creating buildings that are so obviously wasteful? Just a thought.
