Locus Amoenus (Place of Delight) is an ambient audio-visual installation in a public hospital lounge that was conceived to foster calm, focus and place making for the general public. The large screen component depicts a window-like view of a naturalistic landscape that is sometimes roving, sometimes resting, and perpetually animated. This real-time audio-visual artwork represents the local weather through wind, rain, cloud cover and visibility (driven by actual real-time data) and the natural passage of diurnal light from a virtual sun that is synchronised to the geolocation of the hospital site.
