Dynamic Tower is a proposed 80-story skyscraper in Dubai with a most unusual design feature—every floor will be able to rotate independently. The floors will rotate 360 degrees in 90 minutes and will give the building a unique, constantly changing silhouette. Tenants will be able to control rotation speed and direction via voice command. The building was designed by architect David Fisher of Dynamic Architecture. In 2012 the building’s developer put the project on hold and announced plans for a Dynamic Tower in London.
