Short version: Aarhus harbour seen through coloured glass. Fuller description: Standing inside Olafur Eliasson’s installation ‘Your rainbow panorama’: a 150-metre long, 3-metre wide circular walkway in glass in all the colours of the spectrum. It's 50 metres above the city, a permanent art installation on top of Aros Kunstmuseum. (Aarhus International Art Museum). There are 360 degree views. The colours and light and mood change as you walk and according to the weather and time of day. It’s sunset, a few days ago. We are standing in the section with vivid primary shades of red and pink and purple and orange. The walkway ahead of us is empty, the roof curving in a deep purple-pink colour. Through the curving sweep of glass enclosing us, we see the city spread out for several kilometres below a sky dotted with streaks of dark cloud. Across the roofs of the city, we see the nearby harbour and bay. We see across a familiar buildings mid-city, see their windows and roofs. We can see the cathedral and its spire. The skyscraper Lighthouse apartment block in the docklands. Giant cranes. (Industrial lifting mechanisms, not big birds.) All of it is coloured in big rectangular sections of orange and purple tones.
