A small QR code in a lower corner opens a synced livestream of whichever art-piece is on the wall, played through the visitor's own headphones or phone speaker.
The facade stays strictly visual with no sound, as specified. The music is opt-in, on personal devices, and adds nothing to the ambient noise of the street or the neighbouring buildings. For someone who scans, it becomes a private concert on a public building.
Nothing depends on it. The brief asks that we consider how audiences encounter the work both in motion and while paused, including passersby and those dwelling in the area. Someone who stops can listen. Passersby who never scan still see a beautiful, slow-moving painting on the side of the station, complete on its own terms.
The QR code opens a webpage with the livestreamed audio, but can also double as an informative panel featuring the names of the artists, the meaning behind each song and how the artworks sourced their material from 14th to 16th century paintings from India.
