Rotating skyscrapers planned for Dubai and Moscow

Plans have been revealed for the world's first skyscrapers that will constantly change shape due to dozens of rotating floors.

The Italian-based architect David Fisher wants to build the dynamic towers in Moscow and Dubai by the end of 2010.

A 70-storey building has received planning approval for Moscow, and an 80-storey building in Dubai is awaiting approval.

The skyscrapers will be powered by the sun and wind and continuously change shape as each floor rotates around a central axis.

Occupants of an entire floor will be able to control the rotation by voice command, with speeds varying from an hour to three hours for each full rotation.

The buildings will also be fitted with car lifts so that residents can park right outside their homes.

Russian real estate developer Mirax Group is behind the Moscow tower, while the planned Dubai building is backed by Fisher's Rotating Tower Technology Company.
