A giant 15 metre cloud installation has been unveiled at St Pancras International station in London.

The work, created by husband and wife team Lucy and Jorge Orta, has been placed above the station's Grand Terrace.

Cloud: Meteoros is the first artwork in a series of "Terrace Wires" pieces commissioned by HS1 Ltd for the space - which was home to the Olympic rings last summer.
