A sphere of points stands for the devices one phone hears around it. Each appears faint, rises and fades. Lighter points are phones with Atum; when two of them meet, a line runs between them over the sphere: a mutual signature. Once a minute a wave of light crosses the sphere as the minute is signed, and now and then the rim gathers and flares as a root is anchored.
