In recent years we have seen some examples of optical camouflage technology
where a person or vehicle projects on its faces the scenery that would normally be
seen behind the respective face.
Now a South Korean architectural firm, GDS Korea, hope to do that on a skyscraper scale.
Tower Infinity is to be located near Incheon Airport and images caught by cameras
on one side will be projected on the opposite side in real-time to create the illusion
you are looking through the building.
The decision to build an invisible skyscraper close to the airport might be an
interesting one.
