David Fisher's dynamic skyscraper is the last news coming from the far Dubai, source of surprises almost every day.
The skyscraper works around a central concrete core and each floor can revolve (with the wind's help) independently from the others. Fully rotations of 360 degrees for always different shapes of the tower.
Teh central core would be the only component built on site, while the floors' units would come as prefab elements, to install on site.
The motion combination and energy can power the entire building: it could actually power 10 buildings of the same size.
Any air sickness?

For now, full debate on weather the project is doable or not.
