Olafur Eliasson is one of the most renowned contemporary artists. His impressive work Yellow Fog - shown for the first time in New York in 1998 - is on permanent display in Vienna – at the 48-meter-long facade of the Verbund-Gebäudes at the historic Am Hof square. Here, the artwork can be seen for one hour every day at sundown (Please note: the Yellow Fog is not in operation during winter for safety reasons).

Along the front of the building there is a grate in the sidewalk, under which are 32 fluorescent lamps. They immerse the fog, which after sundown rises up the facade every three minutes for a duration of 40 seconds, in yellow light. For an hour each day, the building gets a magical haze: fog, that spreads out over the sidewalk and the square.

Olafur Eliasson was born in 1967 in Copenhagen; he lives and works in Berlin and Copenhagen. He works mostly with physical phenomena, light, reflections, water, and movement. He caused a sensation with his "Green River" project (1998-2001), in which he changed the color of several rivers, as well as with his spectacular ice adornment for the BMW's 16th Art Car.
