This is a physics simulation where every player attracts whoever he upvoted and repels players that he downvoted.
To be exact, the following forces are being applied:
Brownian motion with decaying magnitude
A small force towards the center of the simulation area that increases exponentially with distance
Constant attractive force towards players that were upvoted (proportional to amount of votes)
Constant repellent force towards players that were downvoted (proportional to amount of votes)
Repellent force towards other players, decays with distance^4
Friction to stabilize the system
How you can read this image:
Color represents friendliness: A player who has never downvoted anything will be fully green, while a player who only does downvotes will be red.
Being near a player represents a "good relationship" regarding forum karma. Whether players are direct neighbours or a little distance from each other is not of any significance due to the noise of the Brownian motion deciding on such small differences.
The zk forum cluster:
The only similarly dense cluster is much smaller:
Some rather negative players aren't downvoting everybody, so a loosely connected cluster could form a good distance away from the central cluster:
