SYSTEM NOTE
Probability becoming connection.
A visual percolation threshold model. Not a statistical physics simulator.
OBSERVATION CHAMBER / MVP
Percolation Threshold Chamber
A visual percolation threshold model for observing scattered open cells become clusters and suddenly connect through a spanning route.
threshold
Prototype
THRESHOLD FIELD
Open cells become islands, islands become clusters, and near a threshold the field suddenly connects from top to bottom.
First observation
Drag to open local pores. Hold Shift while dragging to close them. Watch scattered cells become one spanning route.
OPEN CELL / CLUSTER / FLOW / THRESHOLD
open 43.0% / clusters 0
OBS-000 / FLOW / 00:00
OBSERVATION POINTS
Watch the route appear.
- OPEN and CLOSE resample the field around the current probability.
- FLOW tests whether the top edge reaches the bottom edge.
- AUTO searches around the threshold without turning the chamber into a lesson.
DIFFERENCE
Not sand, not slime.
- Sandpile observes local limits cascading.
- DLA observes particles attaching into growth.
- Percolation observes probability becoming connectivity.
OBSERVATION GUIDE
Touchpoints for Observation
Observe scattered open cells forming clusters until probability suddenly becomes a spanning connection.
- Open or close local cells, run Flow or Auto, and compare Cluster, Front, Flow, and Threshold lenses.
- CONNECTED changes only when a top-to-bottom route exists.
- Channel and Porous presets make the threshold moment easier to catch.
This is a visual percolation threshold model, not a statistical physics simulator.
Runs inside the browser with no upload and no registration.
SYSTEM NOTE
cell = open when random() < p. top cluster -> flood fill -> bottom edge. CONNECTED changes when a spanning route exists.
OBSERVATION POLICY

OBSERVATION LOG
Observation logging will be connected with moderation in a later build.
