For the Passerby
Mounted in a standard advertising light box, the work For the Passerby by Mark Niskanen (b. 1991) and Jani-Matti Salo (b. 1984) is based on motion and ephemerality and will appear different to every passer-by.
The subtle changes in the work are produced by three superimposed patterns that give rise to a moiré or interference pattern when they move. The moiré patterns appear differently to all passers-by depending on the height, direction and distance of viewing.
For the Passerby is intended as a temporary artwork. The work will remain in place for the time being, and may eventually be transferred to another location in Helsinki. It is part of the HAM collection of public art.
