If you're one of those people who usually think new skyscrapers are ostentatious eyesores, the Infinity Tower, a 1,500-foot (457 metre) entertainment complex proposed for Cheongna, Korea, will offer a little bit of solace: it will only be an eyesore some of the time. Using a sophisticated system of cameras and LEDs, the building is designed to disappear with the push of a button.
The technological premise is the same one you see trotted out every so often for prototype invisibility cloaks: cameras on one side of the building will project an image to screens on the other. Through careful consideration of viewing angles, the folks at GDS Architects think they've worked out how to create the most dramatic effect possible for pedestrians while remaining in the bounds of architectural and fiduciary reality. In a statement, GDS president Charles Wee said, "instead of symbolising prominence as another of the world's tallest and best towers, our solution aims to provide the world's first invisible tower." It will also have the world's third highest observation deck.
