“Service Unavailable” is a partially cropped lettering based on the screenshot of a found website. It seems that part of the writing is covered by a white plane or an invisible baseline. The letters become almost abstract signs, though the human brain effortlessly adds the missing information, maintaining its legibility. The http error alert itself is displayed deficiently reduplicating the initial error. Attached the to the front wall of an exhibition space this error warning triggers various associations. Is the exhibition restricted in some way or simply closed? Or is it simply a faulty sign on a facade? The literally shifted baseline in the context of the perception of transformation is the main focus of Ulrich Nausner’s work for the Memphis Light Box.Ulrich Nausner lives and works in Vienna.
