Berlin-based artist Olafur Eliasson has taken his art to the skies by creating a “moveable rainbow” above the the roof of the ARoS Aarhus Kuntsmuseum in Denmark.

Titled Your Rainbow Panorama, according to Wired UK it consists of

a 150-metre-long and three-metre-wide self-contained circular walkway with glass that moves through all of the colours of the spectrum. The 52-metre-diameter walkway …[Is located] 3.5 metres above the roof and stretches like a multi-coloured halo — supported by 12 slender columns.

Though it was conceived in 2006, the piece has been under construction until this May when it was finally unveiled to the public. Tinted in rainbow colors, this paneled walkway allows viewers to see the city through a technicolor lens, which Eliasson hopes will allow visiters to “erase the boundary between inside and outside” and find ” a place where you become a little uncertain as to whether you have stepped into a work of art or into part of the museum.” (via PSFK)
