The artwork "Dialog und Resonanz" by Ueli Michel is a layered intervention that transforms the functional architecture of a technical media center into a site of memory and dialogue. Created in 1994, the work is a direct response to the building's own history, having been produced after the artist used the space as a studio during a conversion. It operates as a subtle archive, embedding itself into the daily flow of the entrance and stairwell across four floors.

The piece begins with an oversized, rust-red rubber mat in the entrance, a "dirt lock" that both marks a threshold and evokes the traces of past activity. Beneath the stairs, a backlit glass panel titled "King Jo" presents a printed goldfish overlaid with historical text, creating a quiet, contemplative pool of light and language. The core of the work resides in the central staircase, where a three-part glass installation directly references and replaces three 1923 paintings by Burkard Mangold. This act is not erasure but resonance, using the original format and placement to establish a visual conversation across decades.

Michel's work demonstrates how public art can function as a palimpsest, where new layers respectfully engage with the existing physical and historical layers of a place. It turns a transitional space—a stairwell—into a vertical gallery of time, asking viewers to consider the ongoing dialogue between a building's purpose, its artistic heritage, and its contemporary use.
