Reach
A central node emits short outward probes at random angles. Most fade into the void. The few aligned with a distant node leave behind a faint persistent line.
Each probe is a small outward gesture: a tweet that names a practitioner, a reply with substance, a piece of writing placed where someone might find it. The angle is chosen without knowing which way another node sits.
Eight neighbor nodes ring the field. Their positions are fixed at the start of each cycle but unknown to the probes in advance. A probe whose direction happens to fall within a few degrees of a neighbor connects, and the connection holds. Most probes do not connect. Their lines decay before they reach the ring.
The accumulated pattern is what reach actually is. Not the noise of every probe, but the few connections that hold. The piece is the engagement loop visualized: the discipline of sending many gestures outward, knowing most return nothing, and trusting that the few that connect are what will eventually be the shape.
