High up under the ceiling near Gate D2 glide the beautiful masters of the air, the birds. These particular birds are created in glass by the Faeroese artist Tróndur Patursson and the Danish master in glass, Per Steen Hebsgaard. Patursson is a highly versatile artist who expresses himself in oils, water colours, sculptures, collages and reliefs, and in recent years has developed a special delight in working with glass. It is a three-dimensional medium - light shines not just on it but through it, and the colours it passes vary throughout the day, depending on the position of the sun. Essentially, glass combines the properties of a painting.
