Features showcased
Links and graphs
Link breeds, force layout, and diffusion over a graph.
Links are first-class agents. These models create, age and query them, and let force-layout arrange the result.

NetworksClaude Black Hole
When do personal assistants become the center of the social graph?Humans adopt Claudes, delegate their connections, and watch an agent cluster take over the social graph.
NetworksGiant Component
How many random links does it take before most people are in one connected cluster?Random links pile up between people on a ring while a flood spreads from one person along them. Once the mean degree passes 1, a flood can reach most of the graph.
NetworksPreferential Attachment
When newcomers favor the popular, how far ahead can one node get?Nodes join one per tick and link to links-per-node existing nodes, picked with probability proportional to degree. At the defaults (80 nodes, 2 links each) the biggest hub ends with about 20 links.
NetworksVirus on a Network
How dense must the contact network be before an outbreak reaches most of the population?A virus spreads over random contacts. Each tick a susceptible person with an infected contact is infected at virus-spread-chance percent, and infected people recover for good at recovery-chance percent.
NetworksSmall World
How few random shortcuts does it take to halve the time a message needs to reach everyone?A message spreads one hop per tick through a ring of people linked to their nearest neighbors. Rewiring 10% of the links cuts the time to reach everyone from 16 ticks to about 9.
NetworksTeam Assembly
How long until every pair in a rotating cohort has worked together?Each tick one fixed cohort (every team-size-th person) is active, and each member links to someone in it. The network stays split into team-size groups that fill in until nearly every pair is linked.
NetworksDiffusion on a Directed Network
Where does all the value end up when every link is one-way?Node 0 starts with 100 units, and each tick every node passes diffusion-rate percent of its value along its outgoing links. The links form a tree pointing away from node 0, so it all ends in the leaves.
NetworksNetwork Example
How high does link-chance have to climb before nobody is left without a contact?A random contact network for testing links: each of 40 people links to one random other with probability link-chance, force layout arranges the result, and each tick 6% of links flash orange.
Physics & patternsSpring Chain
How long does a tug on the middle bead take to reach the pinned ends?Eleven beads on ten springs, both ends pinned. The center bead starts 5 units up; its pull reaches the beads beside the ends after about 40 ticks, and the chain keeps swinging.
Physics & patternsDouble Pendulum
How long do two double pendulums started 0.1° apart swing together?Two double pendulums start with their upper arms 0.1° apart. Their lower bobs move together for about 7 simulated seconds, then separate completely.
NetworksYour X Ego Village
Does posting raise only your status, or does it set off talk across the village?A synthetic village of 40 people around you, with roles drawn from your X reply, repost and quote shares. Your posts start bursts of talk that spread along ties, and talking raises status.
NetworksYour X Meme Fatigue
How far does a meme spread on a sparse network when both the audience and the poster can burn out?A meme spreads from you over a sparse random contact network. People who recover may become fatigued and immune for the rest of the week, and so may you, which ends your reposting.
Social dynamicsReach or Relationships?
What does your posting budget build: a wide audience or a circle that comes back?You sit at the center of 48 people. Each action is either a broadcast that about 12 of them see or a reply that strengthens one tie, and ties fade without contact. The run covers 28 simulated days.
