Aura describes a sort of horizon, a circle of definable space but whose detail and reach is ambiguous. In IF a room is structural device: we know we are in rooms, as in the space outside an Inn. This is a room, but it isn’t experienced as one. As noted, there is the suggestion of distance, a hint at an ability to penetrate, but what does the distance look like: is there a wood line, evening clouds, breaks in the snow. We have an Inn, a post, a few directions.
Aura is what we add to fill in the picture on our own, the spatial fill-ins we bring to the digital world.
