two clusters of accounts drift together, spark gold where they overlap, then drift apart and reform. a generative visual metaphor for SimClusters. what's a simcluster?

SimClusters was Twitter's old recommendation machinery — it grouped accounts into thousands of overlapping "communities" learned from the follow graph, then used those clusters to decide what to show you. Nobody outside the building ever really saw a simcluster; it was a vector in a model.
This page makes it a picture instead: two clusters of dots, each its own little community, drifting toward each other on a loop. When they touch, the accounts they actually share light up gold and spark across the gap — then the clusters drift apart and settle back into themselves, until the next pass.
Type two Bluesky handles above and the collision gets real: each cluster is sized off that handle's actual moots (mutual follows), and the gold sparks are the real accounts who are moots of both — the overlap made visible.
