It may not be exactly like the cloaking devices on Star Trek or the invisibility cloak in Harry Potter... Either way, a building that can turn invisible does seem like science fiction and they plan on starting construction as soon as next year (2014)...!!
In an effort to showcase to the world their rising powerful presence in innovation and technology, South Korea is building a 450-ft observation tower in Seoul that can turn INVISIBLE...!!
The tower's facade will come equipped with LED projectors and cameras. The cameras will capture the area around the building, then stitch them together in a panorama to display through the projectors. The result will make the tower seem transparent from the outside when the projectors are turned on.
