Guys this one is interesting. I found this on the internet and felt like sharing with you. A company in Brazil (Suite Vollard) constructed a building in which each floor can rotate 360 degrees. Each building has 11 apartments and each apartment can spin individually in any direction.

One rotation takes a full hour, but apartment owner can set rotation speed through apartment control panel. Facades are made of three different types of glass which give wonderful effects when building spins during the sunset. Cost of each apartment is $US 300,000.00.
