Mark Niskanen and Jani-Matti Salo: For the Passerby, 2019. © Photo: HAM Helsinki Art Museum / Maija Toivanen For the Passerby © Artists Baana, Helsinki For the Passersby is a kinetic artwork by Mark Niskanen (b. 1991) and Jani-Matti Salo (b. 1984). It is installed in the Baana Bicycle Corridor under Lapinlahdenkatu bridge. Mounted in a standard advertising light box, the work is based on motion and ephemerality. It appears differently to every passer-by. The subtle changes in the work are produced by three superimposed screens that give rise to a moiré, or interference, pattern when they are observed from different angles. The moiré patterns appear differently to all passers-by, depending on the height, direction and distance of viewing. The graphic motion seems like an animation or a video, although it contains no moving parts or digital elements. Commissioned by HAM, For the Passerby is intended as a temporary artwork. It is in place for the time being and may eventually be transferred to another location in Helsinki. The work belongs to the City of Helsinki’s art collection, which is managed and curated by HAM.
