Italian architect David Fischer designed the Dynamic Tower Skyscraper so that each of its 80 floors would rotate according to voice command. Fischer wanted to design a space where you could enjoy the sunrise and sunset from the same room. The rotation takes up to 3 hours and is powered by solar panels and 79 wind turbines, with one turbine located between each floor. Almost the entire structure will be pre-fabricated offsite. Construction is due to be completed by the end of 2010.
